Seio 1500 mounting mods (simple)

[edsreef]

Here's a simple mounting mod to mount the Seio's "Tunze Style", from a hanging brackett, and having the ability to turn them side-to-side or up-and-down. All of the pieces came in my box and the only tool you'll need is a drill and bit.

This photo shows the pieces used:

[edsreef]

Put the angle brackett into the swivel mount like this:

[edsreef]

Next, use a pencil or fine tipped marker to trace the hole:

[edsreef]

Remove the angle brackett and drill a hole for the long plastic screw to go through:

[edsreef]

Next, put the angle brackett back into place:

[edsreef]

Slip the hanging brackett into position:

[edsreef]

Put the long plastic screw into the hole and thread it into the angle brackett:

[edsreef]

Snug up the plastic screw and mount the brackett to the pump:

[MK Reefer]

Awesome.. Thanks for the tip :) I am going to do that to my 600 tommorow :)

[niteshado]

great mod for the seios. Was looking for a way to mount them on the swivel with the whole pump in the tank.

thanks Larry

[jfrank]

Very nice. My 2 just arrived in the mail today:)

[tampa-reefer]

Doing it now...

[honl1]

Great tip. We should call this the "edsreef mounting method"!!:D

[CaliforniaDreamer]

Thanks for sharing, great mod. I did something like that but had to use parts from a maxi kit. But I only had enough parts for one. Now I can do the same for my other one and this is a better mod, thanks edsreef. :D

[ridetheducati]

Great job.

[SHOmuchFUN]

Curious as to why you need the angle bracket?

Is it just for the threads?

[edsreef]

yes

[banzai75x]

You get any more vibration noise from using the bracket? I'm using the suction cups right now.

[edsreef]

none whatsoever

[Ewan]

Great mod, Ed. :thumbsup:

-Rob

[thrlride]

Awesome Ed!

[WifesaysImnuts]

This is great. Thanks for the tip. I hate the suction cups.

[ridetheducati]

While using the "edreef-mod", has anyone noticed the 1500s creating a vortex from above? My 1500s are positioned roughly 5 inches below the water surface. The mod restrict how far down they can be mounted. I am running a Maxi12 next to the Seio to prevent the vortex from forming.

[john76]

I siliconed my 820 to a magnet.

[bswedenburg]

nice. where'd you get the magnets? are they the Tunze ones?

[CrystalAZ]

Nice tutorial Ed! I did the same thing to my Seios when I got them. It works great.

Any cheap algae-scraping magnets work ... I used the same thing, except I didn't silicone -- I krazy glue'd. :)

[CyanoMagnet]

I used seios like that in your picture and they both died pretty quickly. Just a thought.

[tfp]

heres my simple mod. i superglued the two parts together, drilled a small hole in the acrylic eurobracing of my tank and used the plastic screw that came with the mounts to tighten it down. for size comparison, thats a tunze 6100 sandwiched between them.

great idea, thanks

[john76]

My magnets are made by SERA. I got them from an LFS near me for $6.99.

[bixo]

not to steal the thread just a quick question....Where do ya'll get the eductor? (is that right) attachmenty that expands the outflow of the powerheads?

[ridetheducati]

bixo,

The Seio do not have eductors attached. Please google SEIO.

[jdg]

There is no eductor attachment for the SEIO; however, the Eductor that can be attached to return plumbing can be purchased from kthsales.com. I believe they're like 25$/each.

Important to get the larger ones too ... the small ones (2.5"x1.5" or so) won't hold them up very well -- not enough magnetic force. I had to go with the 4"x1.5" ones and mount them vertically off of them.

Of course, this too depends on the size of your tank and the thickness of the glass/acrylic, etc. ;)

I've been running my two 1500's for several days now and haven't had any problems like you describe.

My mod is similar except I used the longer "L" bracket instead of the short "t" shaped one. This allowed me to get them deeper in the tank. I have noticed a vortex at the surface above the pump. It hasn't sucked in any air yet though. And only happens when the intakes are wide open,

Mike

[iSpeakWhale]

Good one Ed! I've been asking myself why these Idiots design it the way it is.

[PITSTOP]

Awesome modification!!!! I just finished mine....I love the flexibility of being able to aim it in almost any direction. nice one!

[ridetheducati]

Its not a constant vortex. As I am viewing the display, I would notice that a vortex is forming and a small amount of air is sucked down. I have the 1500 pointed slightly downward. The Maxi 12 is helping eleviate the small eyesore.

I have a BB and I do see a vortex forming below the 1500, which is a good thing. It keep the detritus suspended.

[jeffreylam1132]

Thanks for the info on mounting the SEIO...........

[Cheesy_Puffs]

:thumbsup:

[JRod]

Off the subject...Who's using the Seio's on a wavemaker?

Love the mounting idea. My seio's come Friday and will definately use the bracket mod.

[ridetheducati]

The consensus is not to use the Seio with a wavemaker. They are not designed to run in that manner. There is a thread regarding this matter.

[JRod]

I have seen it mentioned that Rio is going to make a controller and that the SEIO's take a beating on the wavemaker, but I saw in "edsreef" write up that there is a wavemaker in use, wondering what for if the SEIO's are on there. Although at times we read not to do something, how often do we disobey and do it our way. So I was wondering if anyone out there ignoring the "warning" about the wavemakers.

[Stevan]

Which Pix???

The magnets? What did you do and why did yhey die? The mag field?

[ridetheducati]

I am sure someone is running the Seio on a wavemaker. I really like them running 24/7 100% power. In fact, I need two more for my display.

Try running them on the Red Sea and report back.

[TA]

Where you guys getting your SEIO's?
Why is it that the SEIO's I see on various web sites for sale look different than the ones I see posted here? New design?
I've just started looking into them and am curious before I order one.

[Stevan]

Everybody runs them w/o covers on them...The company pix show them w/covers on.

[TA]

:confused: :confused: :confused: :confused:

This doesn't look anything like those posted here?

[TA]

Once the 'covers' are removed it will?

Ahhhh ;)

I see :D

[edsreef]

but I saw in "edsreef" write up that there is a wavemaker in use, wondering what for if the SEIO's are on there

No, I'm not running them on the wavemaker. I had another thread discussing why/why not/what kind of wavemaker they can run on. Hopefully Seio will release thiers soon. I can't do a search right now but when I can I'll post a link to that thread; it's called "Seios can't be run off a controller??".

[JRod]

Search function clogged up, will search later.
Many people out there hoping Seio gets a controller soon. Read somewhere on here that there was talk of one later this month.

kmoses:
That's the one. Thanks!

[kmoses]

Thanks for the Mod.

[AJP]

Great mod, I did this to a 620 works great.

[DrBDC]

Question, they don't like the "hard" starts, they don't like the "soft" starts, what about a variable speed control that puts it through a cycle without actually going off. for example, I use a cole parmer peristaltic pump for my kalk, it has a dial knob for speed control. You can (someone can anyway, not me yet) set up a controlled version of this I would think. That way it would never actually have to "start" and you could set patterns etc.

[edsreef]

DrBDC:
Here's a link for those interested in how the new Seio controllers MAY work; no one outside of Seio knows for sure at this time - your idea is one of the possibilities:

[jeffreylam1132]

I was just wondering can you used the same mounting bracket for all models or each model has it own size brackets.

[kmoses]

I beleive there are different sizes........because
my Sieo 620 angle bracket shown in this mod does not fit in between
like shown in this post so I used a white plastic screw and wing nut
instead.

[jokeloma]

I've got a 75g, any suggestions on what would be good movement maybe a couple of the 620's. Thanks for the mods

[thrlride]

Depends on what you want jokeloma. If you have a softie tank then 820's might be good. If you have some SPS 1100's would be good. If you have SPS and either barebottom or larger substrate 1500's may work for you.

[dsp78213]

Originally posted by jokeloma

I would go no lower than the 820s, probably 1100s. I have 2 620s on my 55g and it provides good flow but I wish I had gone with at least one 820.

I put a 1500 in my tank the other night and it was awesome. But a little too awesome.

They are also a lot bigger than the 820s and it was just too big for my little 55g.

[Stevan]

IMO the 620 will be too small for you. Remember the flow out of these this is very different then regular PH's. Much wider and gentler...it sort of shoves the water rather then an abrupt push (like an MJ1200) that we are used to.

[impur]

I have a single 820 in a 29 gal and its a good amount of flow in the tank. I also run a mag9.5 return pump thru a scwd. I'm considering another 820 or a 620 for even more flow. The tank is a mixed reef with a SSB. Time will tell but i love the 820, definately a great buy. I'm going to do this mod tonight and try it out, the suction cups suck!

[Stevan]

Yup...I've already lost 2 suction cups...they're in my tank somewhere. I'm thinking still about using a magnets so I can move it around and also I don't have much room to hang things in my tank.

[edsreef]

the suction cups suck!

Yeh, but not enough.:cool:

[BOKER420]

hey works good thanks for the idea

[scarletknight06]

I am getting 2 820's for my barebottom 30 cube. Does this mod allow the seio's to be adjusted left to right AND up and down? or just left to right?

[Stevan]

I believe it just goes L to R. For total freedom try the glue on Mag mod ala Tunze.

And I still can't find info about your fuge.

[scarletknight06]

links to this glue on mag mod ala tunze?

stevan,
I bought it from some guy on nano-reef who made it for his 30 cube but never set it up. there are pics on page nine of the "diary: my ultimate cube project" thread if you click on the links.

[Stevan]

Cool, I'll look at your pix. Too bad I won't help too much if it's a DIY.

No link sorry. All you do is substitute a big enough Tank Glass Cleaning Magnet for the suction cups on your fav config mount and use Crazy Glue Gel to glue it on. I like the swivel attached perpendicular to the flat suction cup plate. Just don't glue a magnet directly to the back of the SEIO. The Mag will kill it.

[baz]

Mod works like a champ thanks for the idea..best thing is no more $$ was spent doing it +)

[thrlride]

I need to do mine that way too, just haven't yet. I'm hating the suction cups more and more.

[thrlride]

I finally did the mod today. I did it a little different though. Instead of using the straight piece that EDSREEF used I instead used the long piece with holes in it. I drilled out all of the holes and then attached to that the same way his was.

[johnlewis]

I modified the mod for my 820's by flipping the l bracket over because it is thinner than it is long.

[vmlopes]

hey guys,

Help me out a bit here, I am in the UK and ordered an 820 it appears to have one of the hanging mounts missing (highlighted), they are posting a new one, do i need this to make the mod.
http://reefcentral.com/gallery/data/500/81111post2.jpg

Thank for your help

Victor

[kmoses]

Yes vmlopes you need that bracket to make the mod
mentioned in this article but all you really need is the angle bracket that is part of that assembly. All it really does is act as
a nut though for the screw. What I used on mine was a
plastic screw with a wing nut.
You could always call Rio maybe they would send you the right part. For me though I already had the plastic screws and wing nuts laying around so thats what I used

[johnlewis]

I picked up some used 820's and they did not have the ball joint does anyone know how I can contact TAMM (RIO) to get them ?

[jun_celis]

Last night, I fired up my modified Seio 620 and it doesn't feel like its pushing 620gph at all.

[ridetheducati]

Jun,

What configuration are you running the Seio, horizontal or vertical?

Also, the flow is a lot different than a Maxi, do not expect it to be a fire hose. Plus the 620 is probably too small for your 75g, what do I know, its your tank. Disregard my last statement.

By the way, the Seio running optimally in the horizonal configuration.

[impur]

Its a wide gentle current. You won't feel it much, but put your hand at the other end of the tank. You will be able to feel it still. A good way to see the output of these is to put some air to em for a few seconds. Then you can see the bubble being pushed across the tank.

[Kevin McG]

I didn't see this thread till now but I did the exact same thing just by using super glue instead of drilling.

[jpatrician]

Modified my 2 620s this weekend. Great mod, thanks for sharing this!! I am so glad to be done with those worthless suction cups!! :D

[johara]

One more thanks for the mod. Even a non diy sort could get this right! I and my sps thank you!

[bigfishman]

I love it so much! Great mod!

[mummra100769]

at the shop we have plexi tanks so we cemented algae magnets to the brackets and was able to get rid of the suction cups (which never seem to work for more than a couple of months).

this is a great mod and i will be using it on my glass 180.

[bergzy]

Originally posted by ridetheducati

my 1500 constantly gets the vortex and makes a huge air bubble bath in the tank.

doesnt bother me...so i dont do anything about it...

[jun_celis]

The modification actually looks like to be a Tunze:D . It was mistaken a couple of times.:mixed:

[Badkharma]

Wow what a great mod!! I'll be doing this to my two 820's this evening!! :)

[raskal311]

I did the same thing with my m1100 a few weeks ago but instead of using the plastic screw i drilled the hole and zip tide the two pieces together.

[saltylake]

i am going to possibly order some Seios this week.
I cant afford the Tunze streams. I wanted to find out what people thought of the Seios and if they were happy.
I basically have no flow in my tank and my SPS are in dire need of flow.
thanks for any advice

[ridetheducati]

Salty,

Get the Seio's and be done with it. Its a no-brainer.

Be a doer.

Yup, couldn't be happier with my Seio. Go for it!!

[iSpeakWhale]

I mounted mine on a magnet. No drilling was needed and only 2 parts were needed to mount it. The two pieces that I used (I hope vmlopes don't mine me using his pix) are the pieces that are next to the circled item.

http://reefcentral.com/gallery/data/500/81111post2.jpg

The item on the left is mounted to the magnet and the swivel mount slide right into it. This allows you to take it off the magnet if you ever decided that you want to mount it to the tank rather than the magnet.

[revclyburn]

Hello

does anyone have any size Seio's they don't use anymore? I'll take them off your hands.

Rev

[ridetheducati]

Sure,

Send me $199.99 and I will send you four empty Seio 1500 boxes.

[revclyburn]

is that all,

dag, that's cheap. it's on it's way,

[Leviathan]

I got my 1100's mod'ed the other day and in the system. The mod took about 5 minutes and couldnt be happier with the performance of theses pumps.

Thanks to the thread starter for this simple non-headach causing DIY!

If you turn them off, you have to pull them to the surface to start again!!!!

I dont have to do that, but then again mine are less than a week old.

I would not however advise running them on a wavemaker. I have concerns that the ceramic might give under this type of abuse. JMO

[impur]

Yah i don't have to move mine to restart it. I unplug it twice a day for feeding and never have probs restarting.

[DrBDC]

I'd double check with your hand it's full strength. Then pull it to the top and see if it gets stronger for you. It may not be running full out. Mine as well as the ones my friend has that I help out will push water again after unplugging, but not full strength. If you bring them up they kick in full strength again. I had mine going for a week and it seemed good as I started them underwater. When I hooked his up, they were out of water and I lowered them in and they were twice as strong. So I went home and raised mine and they got stronger. So if anyone thinks theirs isn't running that much current they may want to try that. It could be a qc issue on the old taam production line. ;)

But that said, they've been running constant though on both tanks for over a month without a cleanup yet and no sticking problems that way. That's as much as I ever got out of any maxijet without a cleaning. Reminds me I need to clean my main return and skimmer pumps this week.

The overall strength of the flow. It may be running but not at full speed.

[MadTownMax]

I think he may be saying that there might be some air caught in the pump, lowering it's performance. by bringing it to the surface you blow the trapped air out, and get full performance - just a guess.

[Leviathan]

Ok maybe I am just stupid, but how does bringing the pump up out of the water, flush out air? If anything I would think that this would cause you to have more sucked into it.:D

[DrBDC]

Don't ask me what's happening. Maybe water pressure from the foot of depth? That would be pretty weak though so hmm. I bring them up, let them stir bubbles a little, then lower them just barely under the surface until they kick the bubbles out.

I saw it on another thread on these seio's and tried it to see and was happy I did. I could see the xenia being whipped a little a couple feet away after but couldn't before. Same goes if I unplug them for feeding or anything. So now I just leave them running.

[TA]

What do you seio-owners think about putting 2 seio-1100's on a 65 gal? Will it be too much? I know some of you may say 2x820's will be enough, but I want to know if 2x1100's is too much...:)

Personally I think it is a matter of what you are going to be keeping, or are keeping already.

If its a SPS dominated system, I dont think its going to be too much. I have 2-1100's in my 90 and a mag12 return and I am very happy with the flow I am getting.

If however you are only keeping LPS/softies, then I would consider going with dual 820's

[ReefVan]

Double post...

[ReefVan]

Great bracket mod :thumbsup: .... now all we need is the SEIO 2600 ... :p

I'm kinda disappointed with the flow from the 1500... I've used the Tunze 6080 (2245 gph) as well and it's twice the price but way lighter in weight and much more powerfull...

I guess the price vs flow will be a factor in most people's purchases when considering a large tank i.e 180 gallons plus...

That still doesn't take away from the fact that it's a great little pump at an affordable price albeit it's weight and power or lack thereof... ;)

... and that take the pump while it's running to make the flow stronger.... yes I know it sounds crazy but it works... what's that all about! I think a re-design may be in order....

[Leviathan]

According to the box there already is a 2600!

I just havent seen them for sale as of yet. I have read that it shouldnt be much longer though, hopefully by fall for thoses waiting on them.

And your comparison between the two isnt really a comparison at all since the pumps are not rated at the same flow rate. How can you compare a Tunze 6080 ( 2245gph ) to a Seio 1500 ( 1500gph ) of course the Seio wont be as powerful.

Kinda like saying a MJ600 is weak compared to a MJ1200,,this would just stand to reason.

[Leviathan]

Oops, seems double post are a problem on this thread!:D

[ReefVan]

It just seems way weaker... like much more than a 750 gph weaker.... and that boosting it by taking it out of the water.... what's that crap all about...

[TA]

Ok...got two 1100's.

Did the mod...easy to do. Flow is really nice, but not as much as I expected. Glad I went with the 1100's and NOT the 820's. I don't think they're too big...besides, once I get something in there, I won't pay them any attention!

Here ya go:

ok...just got a m1100. i did the mod to my m620 - no problems. but i think i may be missing a piece. i can't seem to do this mod to my m1100. could someone post of a pic of the modified bracket for a m1100. thanks.

[asmodeus]

Ok i have a question for you reefers out there. I have a custom 62 gal 36x20x20 and i have in there lps / sps mostly lps:
frogspawn , hammer, plate leather, gaint feather duster's, star polyops, sun corlas pipe organs candy cane's 2 types green bubble coral.

SPS i have branching provona, pink digita, clam green horn, pink cap ,green cap, .

I have a 3md plumbed from the basement pushing 4-500 gph and i have a maxi 1200 on the right pushing againt the return which is on the left.

Now I have good flow on the right and hardy any one the left which is good for the lps's. Now what SEIO would you recommand on the tank the 620 to replace the 1200.

Here is a picture of my tank can some one help me out on this one it's hard to find good flow in a small tank.

[dfiddy]

okay well after coming home from this afternoons' reef club meeting where I picked up a sweet lookin pink spotted watchman goby and a nice sized green frogspawn (and a candy cane from a reefer breaking down his tank on my way home! :D) i decided i wanted to do this mounting mod for my 820. I had had it mounted on the left side about 1/3 of the way down and would occasionally have that tornado lookin gap suck some air in and it'd make a crazy noise and shoot microbubbles all over the place.. ***. grr. Not sure what the problem with that has been.?? Any ideas?

Anyways.. I went and drilled the hole for the plastic screw and after completing the drilling I couldn't locate where the heck I put the darned screw!! $#(%& I've tore apart my bedroom, living room, kitchen, and basement tool shop section to no avail. Does anyone know the size of the screw that comes with these guys and if Home Depot or Lowes carries plastic screws?? Not sure where to get another one as I don't want to put in one of these metal guys and have it rust out and kill my tank.

:( :(

Not sure the size...I think 1/4 inch. But they both carry NYLON nuts and bolts. My LHS sells individual pieces for like $0.30 each. Pick up both nut and bolt...if the bolt won't thread (it should if you get the right size), you can always drill out the threads and use the nut instead...it works...I should know:rolleyes:

[TA]

Bring the threaded piece to HD/Lowes/LHS with you. That way you can test for fit. Also, make sure you get the right length, so you may want to bring the two pieces.

[dfiddy]

thanks for the help Tony, went there this afternoon but no real luck.. i didn't see any plastic screws/nuts but i did grab a 1/4" plastic screw looking thing that was at the endcap of the screw aisle that was for mirrors but yea.. then I stopped at the grocery store on the way home to pick some stuff up and came across some.. go figure! a pack of several short plastic/nylon screws & nuts!! they were in the automotive sect. for attaching license plates or something.. woo hoo! perfect.. and for 0.99! :D Lovin' the mod! :)

[Freeskier98]

Thanks for the Mod, Just hooked up 3 820's in my 55. Boy was that a mistake. Sand is going everywhere. Had to throttle all 3 back as much as possible. Mind you I am also running a Mag 9.5 on a Spray bary and 2 maxi Jet 900's for surface agitation. Might be time to rethink some of these pumps :).


Love the mod though! One of the Seio's was missing the bag with the suction cups and the bolt, so I had to use zip ties to hold the 2 pieces together. Still works fine though. Wooh!

If you want to save on electricity and avoid heat issues, probably removing the Mag 9.5 is best it uses 93W. The two 900s only use 17 combined. The three 820s use 54 watts combined.

Your old pumps(9.5 and maxis produced 1410 gph, your new 820s produce 2460 gph for half the electricity)

B.

[Freeskier98]

I am in a PICKLE!

Mag 9 is the return though....forgot to mention that.

Looking into either throttling back the Mag9 or swapping it out for a Mag 7 or something of similar power. No need to be running 900gph through the sump.

Playing around with some combinations today, I found 2 820's (One in each back corner, pointed in a 'V' on the front glass) and 1 MJ900(for the surface), along with the return pump, work pretty good. Still a lot of flow though.

Got the Seio's for 35.00/each brand new, so I got a deal. Might as well just keep the 3rd in case something were to happen to the others :).

[fishman805]

With all the talk about flow..... I reckon I should be looking at the 1500gal/hour models.... 150 gal tank... I've also read the thread/fight about the wavemaker deal and I'm not sure that I even need to have a wavemaker setup to begin with ... I sure want the flow ( I think ) because I do have a brain coral and some shrooms and they don't like flow ( at least the shrooms ) But since these pumps put out more of a laminer type of flow it may not even be an issue comming from the ends of a 150...

Any thoughts??? ( but I am going to do the mod to them when I get them....

[Avi]

fishman...your thoughts are correct, actually. I recently put a Seio 1500 in my reef, which is 120-gallons and it isn't anything like ya'd think a 1500 gph pump would be like. It won't be too strong for the open brain, mushroom, etc. Still, the kind of flow it puts out is good and I'd think you'd be happy with it.

[fishman805]

So going with the two 1500's would work well in my tank Avi??

If you say yes, I'm going to order them.... I'm also taking a trip up to Atlanta to get some more corals for the tank .... Colt... perhaps a bubble... and even thought of a goni ( saw a nice one last time I was up there )...Im thinking the "soft wide flow is really not going to restrict me ....

What say you then..?

[elephen]

Nice little mod :) Takes literally 1 minute or less

[Avi]

I have my 1500 behind the rock for that specific purpose and it definitely isn't a powerhouse. It's water flow is gentle like any Seio, with some more pizzaz. What other flow do you have in the tank? I'd guess that your tank is 60-inches long and if you put one on either side glass, I think you would have a good flow, though, depending on your rockwork, I think you might need some more. In any case, they would be a good start for some quality flow in your tank.

Fishman...if you're gonna get a gonapora, take a look at JENnKerrys' thread on those...you have to target feed them.

My tank is 72" long.... Right now I'm using two Hagen 802's in the corners and two mj1200's directing flow forward and slightly down... I've got a mag2400 for my return comming out of a 3' spraybar shooting mostly straight out and angled slightly down ( very shallow angle down ) The 802's are rated at 400gal/hour and don't quite cut it IMO ... I'm wanting better laminer flow and the SEIO's seem to fit that bill for a good price....

I have checked out JENnKerry's thread... actually been to their website many times... and there is another thread in this forum that is addressing a goni issue.... The other corals that I'm wanting to get are on my "A" list while I'm still "considering" the goni.....

[Avi]

I would get the two Seios, then. I have a MJ1200 with a Hydor on it and close to it I have a Seio820...they're both just for water movement. When I put my hand in front of them, the flow of each actually feels very similar, though, of course the Hydor brings the water around withoug constantly going. This is surprising to me because the MJ is rated for much less power. I actually like the MJ with the Hydor on it. The coral, which are some Pagodas, Palys Clavularia and M. digitata seem to benefit from the "on-off" flow that they get from it. Maybe that's my imagination. But if you have a MJ, try putting a Hydor on it. It surely won't cover a lot of your tank, but it reaches I'd say, a little less than two feet and it's nice to watch when the current comes around to them and their polyps wave.

The Seio1500 is more powerful and the flow is laminar so for your tank, which is nice and long, those would be a good choice.

[elephen]

Get the 2 1500's and set them up on both sides shooting straight across at each other.

[bigreddog]

Excellent mod edsreef. I was using a tie wrap to keep mine from slipping. Took less than 5 minutes and now the tie wrap is gone. Thanks for sharing the tip.

[fishman805]

Avi.....

GregM779 is telling me ( on his 125gal birthday thread) that he would not go with the 1500's but rather would recommend the 1100's.... He's got a 125 running just one of the 1100's.... I think he's thinking that it will be too much flow for my LPS and shrooms..?? But alot of the other corals like the SPS and softies like flow... as well as my polyps ... In your opinion, would I still be good to go with the 1500's...?

Sorry to keep yaking about this .. I just want to be sure before I buy.... Thanks for the tip on the "HYDOR deflector" I finally located them at Marinedepot.com.... They'll go good with my maxjet 1200's

[Avi]

Fish...for you, man, I just stuck my arm all the way into the place where the 1500 is. I put my hand right in front of its output and I moved it so that it blew on some coral (zoanthids) that were about 6 inches from its output. To my hand, it really doesn't feel all that strong because of the laminar character of its flow. When it blew right onto the zo's, while it was too strong for me to leave it like that, it just isn't the kind of "blaster" you'd think a pump driving 1500 gph would be. Unless your coral that your concerned about like your LPS and the mushrooms are going to be situated right there in front of the output, say within maybe 12 inches, or so I really don't think it'd be a bad idea for your tank's flow. I would say that for some LPS, and Pagodas come to mind, the flow would be a good thing. Others, like open brains would definitely benefit from periferal flow that they'd make.

I suppose you have to consider the way that your coral are placed in your reef but I believe that flow is underrated in importance and so I'm still thinking that in a tank that's 72-inches long, like yours, these 1500s are just fine.

I would caution you against a regular waterpump that pushes 1500 gph through a normal powerhead output because of the intensity of that kind of flow. But, I think that because of the kind of flow the Seios create, it's a whole different thing. You could consider placing 1500s in areas where the corals that you're more concerned about aren't located. Or, you could get one 1500 and one 1100 and put the smaller one in the vicinity of the more flow-sensitive coral, or maybe you could move them to be more to the side that you put the 1100 on.

I can tell you that I have an 820 quite close to some Rhodactis and some mushrooms and also some Anthelia, which would particularly show it, and it's definitely not causing a lot of disruptive flow over them at all, and I'd think that the 1500, if a reasonable distance from any coral of concern to you wouldn't make so much of a difference, most likely only an improvement in flushing them clean and preventing algae from getting a foothold on them or nearby. That's particularly important for zoanthids, star polyps, etc.

By the way, I sent you a PM about an unrelated post.

[fishman805]

Well... you shouldn't have... LOL

Thanks for for going to the trouble .... I'm finally convinced that the 1500's are the ones to get .... Especially like you had already said ... for a tank of my size and length...

I'll check the msg...

[fishman805]

I got your PM but your mail box is full so I could not send you a response.....

But yea... good luck with the upgrade... I'm going to do the same...

By the way, I emailed TAAM Inc. about the long awaited ( still waiting ) wavemaker for their SEIO's ... No response yet but if we keep bugging them maybe they'll hurry it up to production and retail shelves.....

[Avi]

I cleaned up the mailbox.

[Meeker]

For the person regarding the Seio 620. Just sand down the left and right side of the bracket, and it'll fit ;P

You don't need to place it *EXACTLY* like the did with the 1500 and 1100, you just need it as a screw in.

Meeker

[fishman805]

I just heard back from TAAM Inc. about their "upcomming" wavemaker device .... I've been informed that they plan on demonstrating the device at a trade show in Sept. but they could not say if and when it will be available for retail sales....

[ryannat1]

I did it tonight! It was super easy but only have one question. It seems like on my AGA Reef ready tank they bulked up their black rim around the top of my tank on the sides. In turn it makes it to where it mounts kinda at an angle(kinda hangs to much) Has anyone done this mod and had to put something in behind the SEIO to stop it from hitting the tank? Later Ryan

[Morgandy]

Thanks! These gadgets drive me crazy trying to tailor them to your own needs.

[Highlander]

I did the mod on two 1500s, and two 820s last night, but instead of using the threaded bracket and plastic screw, I threaded a heavy duty , all plastic, cable tie through the drilled hole and back over the top of the bracket through the higher hole, latching the tie at the back of the drilled hole. Works just as well, and a bit simpler.

[troutbum]

I just purchased the 820 model and was about to do the mod when I noticed that if you attach the " vibration silencer bracket " to the "vertical mounting bracket " you can attach the " swivel bracket " directly as Ed has done in his mod. You gain about a 1/2 to 3/4 of an inch in depth as a benefit, and it does not require the angle bracket with the associated drilling operation for those who Ed's mod but lack the tools required. Not sure if the vibration silencer bracket is included the 620 package, but it is with larger models. Hats of to Ed for starting the whole modification.

[asmodeus]

Well i tried the Mod for the 820 ,but couldn't get the clip in side to slide ,and the other problem that i have is i have a canopy that closes in the tank top ,so i have to go with the rubber clips , unless there is a way to fix it up..

mike

[Avi]

If what you mean by "rubber clips" is the suction-cups that come with the Seios, do yourself a favor and epoxy one side of a glass cleaning magnet to the suction-cup mounting clip that it comes with and mount it on the glass of the tank that way.

[asmodeus]

what size mmagnet should i get and dont for get you have a magnetic driven power head with the magnet , wont this cause problems in the. future


mike

[Avi]

The magnets don't pose a problem for the powerheads so don't worry about that. You'll need a magnet like the widely available Mag-float (but there are other less expensive ones around) that's rated for the thickness of the glass of your aquarium.

[ostrow]

My box is lacking the vertical mounting bracket! Has anyone done the mod with the longer bracket, and if so, how?

[Silencer]

This is a very good mod. I just got two Seio 1500 for my tank today and it only took 2 minutes to drill the holes and now they mount very nicely. edsreef should get an award for coming up with this.

[theop]

Just did my M620 and it works great! I did have to cut the angle bracket to make it a bit smaller to fit. Maybe the sizes are proportioned differenly in the 620.

[Eel-byte]

Just got my 620 today. Just wanted to add a little more movement to my 58. Looks like a nice mod, but I'm missing the 160degree swivel:( I called up Marine depot to let them know, I should have the part by Friday:D Cant wait to try it out!!!!

Where's a good place to buy plastic screws? Any major stores? Home Depot, Menards,....


Thanks!

[Saltcity]

I love DIY stuff......:D

[Silencer]

Does anyone here have a good mod so that the little ratchet clip thing stops pulling out? I've noticed that the part that goes over the tank, in order to fit on the tank trim, is backwards. I have to pull the little panel back to put the bracket onto the tank trim, but once on all you have to do is pull it and the entire thing slides out and the Seio can fall down. It needs to be the other way but then it can't fit on the tank!

Is there a good way to fix this?

[joeychitwood]

Great mod! Thanks for posting the photos. I performed it on an 820. I had to do a little Dremel work on the angle bracket to make it fit, and I cut the plastic bolt shorter.

I wish that I had purchased the 1100 instead. The flow rates can be decreased easily, so the 1100 would have given me more options.

[Toddrtrex]

Same here Joey, I did it to 4 of my 620s. Took me awhile to figure out why I was having such a hard time making it fit. But you are right, the Dremmel took care it it. Took less than 10 minutes to do the other 3. Not about to admit how long it took me to figure out the first one ;)

[arconom]

Is silicone alone strong enough to mount the bracket to the magnet?

[smokez01]

does anyone elses SEIO 1100's make a loud humming noise??

i did this mod and the hum from the pump onto the over hang makes the whole tank vibrate when i put my hand on it

does anyone else have issues with humming???

[joeychitwood]

smokez01, did you mount a couple of suction cups on the hanging bracket? I have two on the bracket and my 1100 makes no noise at all. (I bought an 1100 to replace my original 820 in order to get more flow.)

[Saltcity]

Seems like when the whole bracket rests against the tank or overflow as I have them, the transfer the vibration to the tank. I just loosened the top of the bracket so the mount lays at a small angle away from the tank and it went away...


Hard to explain....:) The suction cups sound like a good trick?

[joeychitwood]

The bracket hangs straight up and down and the suction cups act as a shock absorber between the pump, bracket and tank wall.

That's what I've been looking for since damage having been done to two different starfish in the tank in the last few weeks at the hands of a Sieo 1500 without the guard on it. Howdyadoit, saltwaterfishlover?

all I did was take a hack saw and on the outer cover piece where the directional outlet is I cut the end off flush. I suppose if you wanted to get creative you could recut the other piece and use a hole saw to cut out the opening for the output hole and glue it togethor.... hmmmm

As I'm sitting here reading this thread I am simply amazed at how many people are missing parts when they get there new seios. Does this company not have a QC department???

Did you get noticably more flow without the ring? Perhaps a small increase in flow without the ring. I've thought about drilling a row of small holes around the piece to increase the inflow, much like the DIY Maxi-Jet projects describe. If I do it, I'll post some photos.

I dont get the original mod. I have mine mounted almost exactly as shown, and I didnt need to do anything to my mounts, they came with all the necessary pieces and that was one of the suggested configurations on the box.

Whats the ring? Do you have any pictures w/o it? If you unscrew the retaining ring which holds the impeller in place on the front of the Seio, you can pull the "louvred" plastic flow limiter off. Replace the threaded ring. Now you have unimpeded flow into the impeller zone, but there will be a larger hole at the six o'clock position.

[Lights Are Bright]

Thanks for the reply, but I'm not sure I understand. I unscrewed the ring, and then there is that thing with the 0-ring. What do you mean by louvred?

Thanks

[jay24k]

IT's the piece of plastic that turns to adjust the flow. Just slide it off and put the ring back on.

[Lights Are Bright]

So then theres nothing between the propellers and the outside?

[jay24k]

There is but the piece you can take off you can actually slide to allow less flow if you wanted. If you have it throttled wide open, you wouldn't see much of a difference.

[joeychitwood]

The only time I experienced any noise was when a Zebra Turbo snail had crawled behind the powerhead, and it was rattling against its shell.

Just tagging along.I like this idea because mine tend to fall off the glass with the suction cups.

[giants4pc]

what size seio and how many would you recommend for a 110 (4 feet long) with about 250lbs of LR. It's pretty stocked. My return creates a great deal of surface agitation. I currently use 2 powerheads (not sure how many GPH) lower in the tank hidden behind rocks.

[giants4pc]

just out of curiousity, how many would I need for my 110 heavily stocked reef with about 250 lbs of LR. I have a return pump which powers over 600gph in itself. I have 2 smaller powerheads lower in the tank. What size and how many SEIO's do you think I will need for my tank?

I'd get the 820 and put a Hydor FLO deflector ont the maxijet and that way you should get a good dispersed and intermittently directed flow.

[danferd2002]

Cool thanks

[joeychitwood]

Interestingly, I turned the flow rate down on my 1100 when I added an anemone to my tank to prevent it from roaming around so much, and I developed a fine green algae bloom on the glass within a couple of days. I didn't realize the importance of good water flow in keeping algae down.

[BrianPlankis]

FWIW...I turned the flow down on my 820 and 1100 by closing the ring completely. This only allows two small slots to draw in water and I lost 2 snails, including one very large and powerful one, to the increased suction. A word of caution for SEIO owners out there. I have since opened the rings back up and the snails have no problem passing over the slots now.

I couldn't have mounted mine without this mod. Worst instruction sheet that I have ever seen! You are a life saver. One note. On the 620 you have to cut a little bit off the angle bracket so it will fit into the other bracket. Thanks a million!

[otterpop510]

very cool mod, worked on my 820, aiming to do it on my other seios when i buy them. thanks again!

[susieQ]

OK. I have a simple tank. No returns, bulkheads, sumps, etc. (don't even really know what some of these things are...:D )

Anyway, if I mod and place 2 Seio 820s (which I already own) in each upper back corner do I need a PH down low on the starboard? You know, to kick up the funk into a pile. Or does having the power heads upper back create enough current to do it?

Thanks!
Susie

[Avi]

Susie...you didn't mention what size your tank is. The idea is to get a water movement from your power heads, if that's what you are using for flow, that moves water in every part of the tank. If it does that sufficiently, it will keep most detritus, instead of settling on the rockwork or on the substrate, in the water column so that it can be skimmed out. So, if you see detritus settling anywhere in your tank, try placing the Seios elsewhere, like on toward the top of one side of the tank and the other on the other side but lower down. This may cause a more effective current that just facing one another at the same height.

[joeychitwood]

susieQ, I aim my 1100 slightly downward from the top rear corner of my 54 corner tank, and it does a great job of keeping detritus from gathering on the sand. I've had to adjust it carefully to prevent a sandstorm.

[susieQ]

Avi and joeychitwood: thanks for the replies! I think I have been concentrating too much on trying to keep the ph low to kick up stuff off the bottom. (I do have an 802 near the top though). I am going to move them around.

[susieQ]

One more question-tell me what the blue knob is for and should it screwed tight and opened up some? (I know this is a basic question but I don't know the answer).

Thanks again!

[joeychitwood]

The blue knob is an air-flow control knob. If you want to draw outside air and shoot it out in the form of microbubbles in the Seio's water outflow, you can adjust how many bubbles are formed by turning the knob. It's rarely, if ever, used in the salt water hobby. Close the blue knob completely.

[reefpod]

I bought a 650? and it was pretty darn loud. Much louder than a maxi jet. Is this normal or did I get a dud?

[joeychitwood]

Both my 820 and 1100 have been silent, except when a large Zebra Turbo snail crawled behind the powerhead.

Are you using the suction cups in the mounting bracket to cusion the vibration?

Yes, but it doesnt seem like vibration, just plain noise from the pump.

[Shooter7]

I can attest to cirolanid's comment about the snails. I had closed up my seio 1500's to tune back the flow a little as they were drifting the sand in my new tank. Since adding snails, I have already lost a half dozen to these powerheads. I will have to try and adjust them so that I can open them up and save some future snails' lives.

[Nash37]

I just completed this mod. Awesome! Thanks!

Has anyone had a problem with the Seio (820) causing a vortex and sucking air causing micro bubbles to be distributed throughout the tank? Other than being visually annoying, is this bad? How should I correct it?

Thanks

CJS

[Shooter7]

Yup, mine does the air sucking from the surface several times a day. :(

[Avi]

You'd just have to lower it a little...that stops the "whirlwind."

[Shooter7]

It's as low as it'll goooooo......

given the mounting hardware and mod

[Skepperz]

Is the flow reducer turned right down?

[Shooter7]

How do you do that in a reef ready tank? You'd have to raise the level of your overflows. :confused:

[Shooter7]

Well, I finally got in there and opened mine up a bit. When I got home from work I literally had a pile up of dead or dying snails on top of the pump. So, hopefully this will even out the suction a bit, although they are not completely open. I was still getting a fair amount of sand movement with them full open and don't want that. Does opening them up have any effect on lessening the surface sucking?

[easyguy329]

Using the Seio on a wavemaker or any timer risks the chance of breaking the ceramic shaft. They are way to torque to consistantly go on and off.

[marilynrn711]

I have been trying to figure out how to remove that detachable cover on the bottom . I removed the housing cover and unscrewed that bottom but cant figure out how to make it look like a tunze.

[iaJim]

If you are talking about the directional vane attachment, it just twists off. I had the same confusion; it just seemed to be one piece and I tried to screw it off. That, of course, took off too much. Just hold on and twist it off. I'm assuming that you have already removed the housing box that surrounds it.

[SunnyX]

Anyone mount a Seio using this method one a Euro-Braced Tank?

[3S1K]

I just got done doing the mod and it was very easy,actual labor was only a few minutes.It took a little longer because I had to remove my pumps and dry them before I could start.

The only con I could find was the bracket doesn't adjust long enough to clip onto my tank so I had to flip it around.The notches are backwards now letting it slip on the grooves.Other than that I'm satisfied:)

[3S1K]

Whats a Euro-Braced Tank?Maybe thats why I had some problems,mine is an AGA tank and you can see a picture of the brace here.

This is the same problem I had. I ended up buying a pair of magfloats and siliconing the ball-and-socket type bracket part to them. I was just too afraid that one day when I bumped my plumbing or power cord the ratchet would come out completely and turn my tank into liquid southdown. As a bonus I get to mount my seios lower now, since they no longer rely on any bracket to hold them.

If you look at the pics below you can see the euro-bracing around the top of the tank...

I can't even mount it like this on my 75 because of the 2" lip around the top. I need the screw to clamp down on the edge itself unless I want to use the suction cups. My modded seio is mounted to the edge of my built in overflow, because that's the only place I could get it to mount using this mod.

[causeofhim]

Nice mod. Thanks

[poopsko24]

I got two seio 1500's , you guys think a mag float 350 will be good enough to hold these up on 1/2" glass ?

[Spartan]

So did a controller for the seios ever come out? Have not been able to find one. Rumor was that it was due out at the beginning of this year?
