Does anyone throttle back their Vortechs?

[JG1]

I have two MP40w's on a 48x24x20 running on NTM.

The flow is pretty crazy at 100%. Was debating throttling back to 75% but don't know if that's sacrilege with these pumps....lol

I was running RC for a little while but I think circulation and randomness is better with NTM.

Reason I say is I don't have great polyp ext during the day yet, but at night everything is extended and the polyps look like they're being blown violently back and fourth. Maybe they love it, I dunno.

I don't have much LPS but I have a nice green/purple frogspawn frag that I can't make happy because of the flow. Just added a pink boobies chalice and at night it's sweepers were being blown everywhere.

i have one on my 4' 120, with sps and lps, its def not enough flow, a second one is in the future. seeing the flow of one, i think two dialed down a bit would be perfect, plus hopfully a little more quiet.

[abrian]

I have two MP40's on my 120 and keep them at full power. I tried turning them down a bit (~70%) for a while but started noticing some of my acros losing tissue at the base so turned them back up to 100%. The tissue loss stopped, so I will keep at 100% permanently from now on. Just my anecdotal experience though so take for what is worth.

[joker295]

i had 4 mp 40 on my tank and had them running at 75% and didnt see an issue.. i then put them on 100% and had a small sand storm so dialed them back down.. it depends on the setting you have it on as well ... i have mind on reefcrest and the randomness is great..

[evoi19]

I have one mp40 on 90% in lagoon mode. That's accompanied with two tunze 6045 on a 4ft 90gal. Would love to add one more mp40 in the future. :)

[JG1]

I just set the NTM @ 75%.

It doesn't look like such a storm in the tank now.

[chercm]

is the ntm light purple in colour on the vortech controller?

Hmm, I'm not sure. I change the modes through my Apex controller. I haven't touched or looked at the vortech controller since I set the tank up.

[A. Grandis]

I don't have any SPS nor other type of hard corals, but I can tell you that you'll never have more flow in your tank than in the ocean. It's just like lights. You simply can't bit the sun's power with artificial lights.

I have 2 mp40's on my 65g running at 70%

[silentscream]

@JG1

My tank has the same dimensions and my 2 MP40w's run at 65-75%. I don't have enormous amounts of rock and my SPS are still pretty young. This has been the best flow for me considering my tank's current level of maturity. I imagine that once my acros are no longer frags but branching colonies, I'll have to bump up my pumps to 100%.

what mode?

[silentscream]

Reefcrest. I don't have the new ES controllers, otherwise I hear good things about "nutrient export" mode

edit: reefcrest in anti-sync

07 3 series :)

[Justdrew]

I run my mp40 about 60% and the mp10 about 80%. Anti-sync reef crest usually in a 37 gallon SPS tank.

[westreef]

Both of the mp40 on 90% in RC mode.

[cham]

I have two MP40's in my 4' 120 and run them on constant speed 100% with two maxi mod'ed power heads in addition to that.

I'd like to find a couple MP20's I can put in too.


It takes weeks & very careful positioning but none of my corals get blasted, the flow is random and I get very little to no detritus on the bare bottom, saves me some time with the turkey baster.

Jeez, must be a hurricane in your tank!

Do you have ANY lps?

[Jabrams]

I have an mp10 on full blast on reef crest setting.
14g bc sps

[Rosti]

3 pm40s at 100% reefcrest mode on 48x24x30 with DSB and no problems

[cham]

Yes, a plate, 8 or 9 acans, couple hammers, couple anemones and some other stuff.


Well thought our chatotic flow can make a tank handle massive amounts of GPH without making any corals uncomfortable. I get great PE from them all.

[divewsharks]

I have an 90G with 2 mp40w's and 2 mp10es'; I run the mp40w's on Lagoon @ ~70-75% and the mp10's on Lagoon ~50-60% (they are focused behind most of the rockwork). My tank is SPS dominated. Based on the current placement of the vortechs, if i bump up the flow,a good amount of sand is displaced.

[DopeCantWin]

I have a single MP60 on a 90. I keep it around 75%. When I kept it higher, the fish would never come out.

[Ostentum]

Until the fish are stuck to the glass you can never have enough flow. Running 2 mp40s on Reefcrest Anti Sync at 100% on a 110g. Corals love the random flow. Also running a BB so no issue with sand blowing around.

[Toadally]

I have an MP40 and two MP10's that I run at 100% on my 57 Illuminata. Our club hosted Dana Riddle last fall and he did a presentation on flow. According to some of the discussions that we had, the more flow the better for SPS dominated systems.

An article on flow by Dana was just printed in Advanced Aquarist magazine.

[oscarslr]

3 mp40's 100% reef crest, 6 k4s on my 225

[MammothReefer]

I typically run mine at 100% (mp10 and mp40) however when introduce something new sometimes find i have to dial back the mp40. Tanks a bit on the small side for 2 tunzees and 2 vortechs ;)

[chrisqueenz]

I have to 2 Mp60's on Reefcrest in my 265 and its great. Fish love the random flow, the more "Organized flow" you can get the better IMO

[j-dizzle]

Have 1 mp40 on 100% rcm on my 72g and can't wait to get another

[cediss]

Getting ready to build a 120 (48x24x24). Was thinking of two mp40's versus one mp60. Mainly due to cost of buying 2 mp60's. Now I'm thinking I just need to spend the cash and get the 2 mp60's. Planning on mostly SPS. Guess I could just add the second mp60 later, but it may pass the wife's budget screening now at initial build! Lol!

[reefkeeps]

This is mine at 75%, two MP40s and a 60

JMO but two mp60's on a 120 is gonna be overkill

[skh]

I second this. I'd talk to someone at vortech before you buy an mp60 for a 4' tank.

[sullyfish]

I have 2 mp40's @ 100% in my 180 AG and works great. My frags are finally getting big enough to impede flow in the middle, so I just got a see swirl that will add some more random flow in that dead area.

not sure if anyone uses the night mode option, mine goes into night mode around 10pm.

We need pics

[JG1]

I tried the vortechs back in Reef Crest mode @ 100% and I don't think the tank had enough flow. Put them back in NTM @ 75% and it seems perfect.

[cediss]

Wow! Glad I asked. I didn't think I'd get that response. I'll do more research then. I was thinking when my sticks fill the tank I would need that much flow! Thanks for the advice.

[chercm]

This is mine at 75%, two MP40s and a 60

nice one ....

[gmpolan]

Two mp 40's 75% reef mode, two k1450's in my 150 ( 5 x 2 x 2)

[mos90]

2 mp10's at 90% in tidal swell mode in my 28g nano. i tried less but was having problems with stn at the base. might go to 100% . was thinking of switching to nutrient transport.

[pnavarro170]

got an mp40 and mp60 on a new tank, 4ft 120. with DSB. at first i couldnt run full blast on 60 but once the sand settled down i now have them both at 100% on short pulse. i also have minimal rock work so lots of open area for flow to go. but dont forget to give the wetside a vinegar bath more often you will see a huge difference if you even go 4 months without a cleaning. just my experience so far. below is a pic(not that you couldnt see it)

nice one ....


Thank you sir, sometimes it makes me a woozy watching it =):hmm2:

[Stanley-Reefer]

I run my 4 mp40s in my 175 at 100% lagoon in the day and 100% RC at night. All are in sync

I leave the ones in my 90 on 100% RC all the time.
