I'm running 6 radium 3 400 3 250 on a 500 gallon I've always admired tanks and the way t5 look exp... Ati my question is u guys think it would be a wate of time or not be better? Also my electric bill is crazy I'm curious if the t5 would help that as well ....I basically asking if it would be pointless or a noticeable better change?

Why not look in to LED's? Would help your electric bill and save on the cost of bulb replacement.

On the other hand, if that was the way you wanted to go, I love a MH/T5 combo. Gives the best of both worlds IMHO. I did however make the switch to LED's and am happy I did.

But my Edison bill is 1500 a month I do have a lot of tanks but still it hurts Im not really asking or trying to get my bill lower just wondering if it would be a perk with switching to t5 a lot of tanks that I admire are t5

I think they both look great you should do the ati hybrid..the color combinations makes a big difference with the looks..

I'm not sure you would save money and I doubt your coral would do *better* under T5 compared to 1800 watts of halide.

What are your dimensions? Sounds like you would need a lot of tubes.

I have had them all. I liked mh, I did have a problem finding the right one for the color I like. I added t5 to supplement. 400w mh was getting costly. Setup new tank with all t5, eight bulbs. Loved it. You can mix and match colors to really dial it in. When leds came out, I really liked the royal blue color. I switched half of the t5's out and went with 50/50 t5 and RB leds. It looked good. I was happy but the leds could not compete with the t5's. You need to have reflectors or optics for leds. I switched to some more leds and only two t5's about a year ago. Not digging it. Next week I'm going with 5 rows of RB and NW leds, their on c channels and 4 t5 bulbs.
You did not mention why you have 3 400w and 3 250w.
If you are planning on keeping sps with t5 you'll need 6-10 bulbs. If you have a 6ft tank then use the 5ft bulbs.

The only way I would think the switch from halide to t5 would benefit the tank is if there is dense coral growth and a lot of shadowing. Nothing penetrates dense coral growth like t5.
But you would need a load of t5 over a 500g. Not sure how efficient that will be. As for
LED, you'll need a ton of t5's anyway to eliminate shadows. Not worth it.

BrentH

My tanks 8 feet long 4 foot wide and 2' high so I would need 3 or 4 48" 8 bulb units ..... I have the 400 watters in the front and the 250's towards the back were there not enough lights dobro the tank being so wide might be a bit over kill. BIt my tanks lit well

billyzbear
02/12/2015, 11:59 PM
8 bulbs for 2ft wide is good. You would need atleast 6. They don't have to be 4ft long, 3 feet long will work. The ATI fixtures are nice. You see t5 units around a lot. The growers use them and a lot of reefers are selling them to get leds. Each bulb must have it's own reflector and you want the end caps to be sealed. If you have a canopy you can get retros, which is the ballast, sealed end caps and reflectors. Just mount end caps inside and wire them up. A cheaper route than fixtures. You can buy the pieces seperately.
The very best thing about t5 is you can change a bulb to get the color you want. Less heat and electic then mh. But you need to change more bulbs.
That's the reason I switched to leds but now it's going to be half and half.
Where in socal are you?
Sounds like a massive tank, pics?
You must have some shaded areas with only 3 mh across 8 ft.

billyzbear
02/13/2015, 12:01 AM
Sorry, to answer your question right. You would need 6-8 bulbs per 2 feet wide so four units either 3 feet long or 4.

BrentH

My tank is 6ftx8ftx3ft.

I was running Giesemann Spectra 6ft units. 9x400W Radiums. 12x80W Blue T5.

I switched to 4x4ft and 2x3ft ATI Hybrids.
My electricity bill has dropped to half. Tank temp from 26.4C to 25.2C.

The PAR is way higher- believe it or not, I bleached my lps on the sandbed with 50:50 blue + and coral+.

I was told I couldn't run t5 on a 36" tall tank... WRONG!.

I am running the led on rb/b at 30% and T5 at 80%!.

I am slowly changing out the coral plus to actinic to reduce the par and increase the pop!.
I will slowly ramp back up to 100% t5.

The ATI Hybrid is a par monster!!. You can't go wrong with it!.

so halides about 2000 watts-12 cents kw-25 cents/hr. 6 hrs a day= $45 a month for halides. + your other bulbs. possibly chiller cost, in my tank it doesn't run in winter and barely in summer.

billyzbear
02/13/2015, 05:21 AM
I got it now. Do you like the 250w? You could keep them in the middle and have t5 along the sides. Doesn't really make since to keep 400w as they use alot of electricity.
The ati hybrid cost alot. The program that comes with them looks really cool.
Kessils with t5's would be a good alternative.

Yes it is. Understand thank I am not talking about light penetration in general, because a 400w halide would show higher par further from the source. I am speaking of the complete coverage that a t5 can provide. There are no shadows and every inch of coral get illuminated. This is most apprent with corals that have a clustered growth pattern, and grown out reefs with dense growth in general.

If your tank is doing well, why change? I've made this mistake more than once. What may work for one person, may not work for another. Halides are the bees knees changing from them because of power concern is one thing, changing from them to improve lighting is another.

Personally, I love T-5s, I think they are a great light source with great color options. However, What you have (000 watts of radium halide) can't be improved.

Don't know.
If you spend some time in a tank with par meter, you will see the uniform par spread across the tank and each coral using t5. I am not for halide, or t5, I am for both. I run a 400w radium on a 32" cube. If I don't run t5's in addition you can see the par drop off more steeply away from the halide hotspot. You also notice more shadows on corals and between branches. IMO/IME the t5 helps illuminate the coral fully and increases its health. Just because my experience hasn't been confirmed by a study, doesn't exactly make it misinformation. I do understand your concern though.

I switched in October. I bleached a few LPS, but SPS were fine.
I think it was more the LED setting.

It's a great light. You would do well with either the hybrid, or even the Sunpower T5 if you wanted to keep costs down.
The Hybrid adds a beautiful royal blue/ violet shimmer though!!.

Mo

Moser
02/14/2015, 06:11 AM

Exactly!, care to show us your facts and not baseless opinion?!.

My opinion is based on my 1000Gal SPS system. I was always told SPS wouldn't grow with T5 over 30" and even that would be a struggle, so I never tried!.

I ran 400W Radium for 4 years and just switched to ATI T5 Hybrids, thinking that the LED would help me punch down…..

Even with 9x400W radiums, I could see SPS colours vary due to proximity to the bulbs. i.e. relatively shaded areas are less intense in colour.

With T5, the colour is more uniform and the growth pattern doesn't follow the light source!. The coloration is more solid and even and penetrates between branches much better, because there is no point source!.

I don't even need the LED on a 36" tall tank!.

Whats your evidence of your opinion please, since you called me out!…….

WRONG!
Radiums are beautiful, but they lack low end pop!. Thats why many used to add UVL super actinic.

With T5, you can mix and match. With a Hybrid, you add royal blue and violet, which Radiums cannot match.

You also get a completely even spread of light..

To say Radiums cannot be beaten, you have to have tried all of the rest to have that conclusion…. when did you try all of the rest?.
What was your opinion of the ATI Hybrid?.

That depends on what you compare.
Over my tank, 9x400W Radium would be considered a lot of light, but wall to wall T5 puts out more PAR and if all the tubes were GE6500, there would be no contest!. So, it depends on what you compare.

Mo

jackson6745
02/14/2015, 10:21 AM
Mo, this is true. My experience using a par meter is with the sfiligoi and spectra units. The T5's absolutely suck compared to an ATI fixture. PAR is half of what an ATI future puts out. I actually do run 2 ge65k and 2blue plus to get more par. I know what properly driven t5's are capable of though.

On my 32" cube the SPS are really starting to fill out. Shadowing has been a problem, I am actually getting STN on shaded portions of coral. I don't lose the whole coral, just the shaded part will recede. I am seriously considering getting rid of the Giesemann spectra adding 10 or 12 tubes over the tank. If I can find a 10 bulb ati or maybe run 2x 6 bulb fixtures.

The thing that's holding me back is my colors. Most of my SPS color is spot on. I am afraid that if I go all t5, I will fade colors, or maybe lose some of the vividness that I get under the radium. What do you think?

kevensquint
02/14/2015, 11:08 AM
I use both 250 radium's and a set of 6 T5's. I can grow my sps with either/and/or. From my experience, best colors, growth comes from mainly T5's with a 3-4 hour dose of MH. I was doing the opposite and colors were not as deep. IMO, the lack of piercing intensity of the T5's help reduce the paleness of my colonies in my low nutrient tank. So in fact, this precise method may apply depending on your other variables like nutrients, Alk level etc..

Richard, your tank is sweet.

I am reluctant to say to anyone who is happy, to change anything. We always think we can do better, but the answer is that if your colours are good, don't change anything!.

If there is a problem, then it might be worth trying something different, but a major change to a system WILL de-stabilise it for a while.

That said, if the tank is generally running well, it will recover well and imo, colours with T5 can be tweaked to your taste and are better than any other light source. If you add the LED from the ATI Hybrid, you can't beat it.

The MH shimmer is slightly more natural though- you can't beat that!.

I am glad I switched my lights. I am VERY impressed with them.

It's all a balance. If nutrients are low, T5 is the best.
If you need more PAR, add more White tubes.
BUT I only used blue + and Coral + and it was plenty. I'm now experimenting with actinic tubes.

It would be nice to hear from Joe Peck. He has experience with heavy amounts of actinic T5. The colour is so nice with them, I'm adding more and more…
mind you, I have 48 tubes over my tank, so I can chop and change. I was told that actinic T5 does nothing for a coral's biology- but it doesn't seem that way from what I am slowly seeing!.

Lovely tank, Kevin.
I can't remember if you posted your filtration etc previously?.
Really like it.

Do you run actinic T5?.

Brent, it was me that said I was removing some coral+ tubes to add actinic and get a little more pop / reduce par a little. I am running the T5 at 80%, but will increase to 100%.
There are conflicting opinions on the value of actinic T5….

Mo

kevensquint
02/14/2015, 04:18 PM
Mo, its a 75 peninsula BB with remote DSB in sump and skimmer. That's all. Actinics are useful, I tried 4 actinics out of 6 tubes and I got some bleaching on a few branches. Its not so much PAR, but PUR. The 420nm wavelength is a serious photosynthesis spectrum even if it looks dim to humans.
My best results are 2 URI actinics/2 blue +/1purple +/1 coral+

Moser
02/14/2015, 04:24 PM
Are the URI similar to ATI actinics?.

I was planning 3Actinic/ 3 blue+/ 1coral+ / 1 purple +.
Coming from Radiums with Blue plus tubes, you can see I like it blue!.
I will consider replacing 1 actinic if it is too much and possibly add a coral+ or a blue+ to get the right colour/ brightness in the tank...….

Mo

kevensquint
02/14/2015, 04:27 PM
I have a spectrometer and no they are not identical. I cannot say which is best tho. The UV's...(sorry I had vho in mind) seem to have more low NM wavelengths, but my corals enjoy ATI equally IME.
IME, you might want to try the look/results with one more coral + in place of one actinic or blue+

Moser
02/14/2015, 04:42 PM
I started with 50:50 coral+:Blue+.
Nice place to start, but was very bright….

I added a little bit of red from the purple+, which brought out some pinks.
The actinics made everything really pop, so I added one more. I'm at
3blue+, 2Actinic, 2coral+ and 1 purple+. I was thinking to try one more actinic, but maybe I'll stop if it does cause bleaching…. I need to adjust the LED's yet too!.

I believe they did discontinue them. I wish I could find a 36" 10 bulb unit.

Moser
02/15/2015, 02:33 AM
As far as I know, 10 tube power modules are available.
My LFS has a 24" 10 tube. Sunpower only go up to 8 tubes.

Hybrids are only available as 4 or 8 tube.
I looked at 60" units, but my tank is 72" across and I have acro's on both side walls, so I needed better coverage. I decided to mount units Front to back. I had 86-96" to cover due to internal weir boxes.

I could have used 60" and 24" on the sides and 60" and 36" in the middle, but that would have used 3 different lamp sizes, so I went for 36" and 48" units instead. I have two 48" units in the middle.

I have almost every inch covered!

Moser

About 8". I would ideally have it even higher, but the hanging wires drop it about 6".

If its T5 alone, then you can run it even 2 or 3" over the tank, but the LED needs to be higher.

There are alot of bulbs to choose from some that haven't been mentioned.
GE daylight will bring out the yellows, high par too
geissman actinic plus is between blue plus and actinic
geissman azure is a new bulb between blue plus and coral plus more green
KZ cost more, thier blue is bluer than blue plus, purple has some nice actinic added, new gen 2 is a little bluer than coral plus
From my testing, too much true actinic caused some coral to color shift also some sps turned more green. Par meters don't really measure thier intensity. Two out of eight is plenty. I would not have them on by themselves. I think it adds to color shifting.

Moser

With 28 double 410uv led and usual 2 actinic plus t5 over my 150g a normally light orange chalice shifted to a light purple. Many zoa changed color and sps were shifting to a shade of green. This was over 6 months of use. No bleaching.
You should acclimate your coral to new light source.
Mo's blulb combo is good, sure. The beauty about t5 is if it's not blue enough take a coral plus out and put in a blue plus. It helps to not have like bulbs next to each other.

My LFS, apparently has a dimmable 24" 10 tube ATI power module on their DT.
They don't have the onboard computer, but I don't know if he was just sent the non-dimmable one and he hasn't realised they never run it as a dimmable unit! :strooper:

The sun power only goes up to 8 tube- dimmable or non dimmable. They never made 10 bulb fixtures…. but you could do a 4and6 tube sun power, or 2x6bulb units!! and it might still even work out cheaper than a 10 tube power module!. :frog:

Have you given thought, or do you have the ability, to transition lighting? I'd drop the 400ws and replace each one with ~300w of t5 (maybe a 8x39w). Relatively, I'm getting better growth, spread, temps, and coverage out of 4x39w than 250w MH on my 40br. The Radium/T5 combo would be great.

Nice tank, I missed it but went back.
You'll need to play with the bulbs some to get what you want. I like the giessemann actinic plus. Ati blue plus is like meat and potatoes. Since you have one fixture coming you'll have sometime to get what you want. To start, 1 coral plus, 1 purple plus, 1-2 true actinic, 1-2 actinic plus and the rest blue plus. Seperate the coral plus and purple plus by atleast one blue plus. You may want some yellow, the GE or another white bulb.
I probably missed it, what bulbs do you have now?

Richard if you are going for T5, get 2 x 6 tube Sunpower units. Either dimming or non dimming. If you want only 10 tubes then get 4 and a 6 tube units. An 8 tube unit with 2xReef brights on either side is more or less like a 10 tube unit.

FWIW, I wouldnt be worried about replacing so many tubes every 8 months...I replace my ATI tubes well into a full year. Scotty runs his T5 tubes like every 16 months or something...and his tank is a TOTM tank.

Thats IF you really wanted to switch from halides... ;)

Pricey, but a nice piece of kit. It gives you shimmer, royal blue and violet LED ( which nothing can match), Great PAR, T5 variety and coral coloration and programmability.

Nothing wrong with MH/T5 though- apart from heat and electricity bill- they're tried and tested.

The fans wear out and the ballast can go bad.
3ft, try to get all the same. A three foot fixture will need to be higher than a four foot to cover the extra 6" on the sides.
Usually people have them mounted 3-5" above tank. To raise and lower I thoght a pulley system would be cool. It's doable but I haven't seen one.

billyzbear
02/18/2015, 02:17 AM
I would think side to side.
You can do some cool illusions of depth as you look into the tank. It would help if you angle the fixtures in an upside down "v" above the tank. Like a 20 or so degree angle but not mandatory.
You could hang with a hook in ceiling and a chain to fixture. When you want to move it up reposition chain on hook.

Don't really want to switch but I think the tank will benefit from the T5's. The growth is becoming dense. I even had to get silly with the flow :). Running 4 vortechs and a Grye 130 in there now. I really want to grow this tank into one blob of acro :twitch:

Which daylight tubes are you running? I use at least 2 ATI Aquablue specials. These have significant spikes in the green/orange/yellow/red parts of the spectrum and consequently brighten up the tank. I also like Richards idea of using a GE 65K tube; it is visually quite bright.

BrentH, which MH bulbs are you using?

You can use the fixture you have, I would suggest you get all the same or atleast two that are the same. It will make it alot easier when it comes to getting bulbs and will look more uniform over the tank. So get another one like you have then get two 4 ft 10 bulb fixtures or get three more like you have.
You can also get reefbrights, royal blue and or other color leds and put them inside or hang them on the sides of fixture.

14k phoenix bulb really isn't blue. If you have 3 blue plus, 3 coral plus, 1 purple plus, 1 actinic and it's not bright enough. You could swap out coral plus with ge 6500k or another white bulb. The difference between GE and coral plus, GE has more green, yellow, orange and red and less blue. A GE looks good when flanked with blue plus. Corals use more blue and red to grow. Fish and some coral look better with all the colors. The actinic plus looks like blue plus but makes the coral pop more and is a lighter shade of blue. Par is lower than blue plus. If you read that link, blue plus is close to the highest par with spectrum meter. Par isn't everything but that is a long discussion. I thought you would want it bluer...
Side by side? Do you mean length wise across front?
I guess you could go length wise front to back but it will be harder to balance the color across the front of display.

Frying coral, bleaching? I would have to know the hole story before I could comment. Generally no bleaching. You will need to acclimate coral to light. Have light on for 2-3 hours then off for a couple of hours. Repeat for one day. Two weeks should do it. You could also raise lights so they won't be soo intense.

The ATI fixture is amazingly efficient, though while PAR is high I did not fry any of my corals when moving from LED. I was 350 PAR up top with LED, now 450 PAR with the fixture 12 inches above glass lids, 250 down on my sandbed, and I have a deep tank.

+1

If it's not bright enough, Aquablue specials will make it much brighter.
GE6500 are too yellow for my liking.

Be careful though, too much and they wash out the colours! A bit like 10k v 20k I suppose!

You can offset the 6500 my adding blues. It has the strongest PAR- non ATI.

The ATI Aquablue Special is a whiter bulb- still strong PAR and brings out pink red nicely, but fluorescence can be washed out a bit.

The ATI Coral+ is supposed to be the balanced bulb, a mix of everything. Slightly bluer than the aqua blue special and a hint of pink.

Those are the 3 "white" tubes to choose from, depending on how blue you like it.

I was told to try 50:50 mix of blue plus and coral+. That was a nice starting point.
For me, it lacked a little warmth so I added a Purple+ and that was nice.
I then saw the effect of actinics, which looked very nice, so I have slowly added actinics- they just give an extra fluorescent pop.
Also, my PAR was very high with the 50:50 mix, so I could afford to drop it a little and change some bulbs out at the same time to mix colours.

I would suggest experimenting with a couple of different coloured tubes. I have only recently swapped to T5 on my main tank, so no tube change, only swap outs.
I have had 6 Blue+ tubes on my frag tank for 18 months without a change and there is no problem yet- similar to Scott's experience with T5.

I swear I replied last night but my post has disappeared....:worried:

Anyway, It looks like you have just enough space between the fixtures to allow the hot exhaust air to vent out properly. IF you notice the fixtures getting too hot then you need to pull them apart another 1inch or so if possible.

I agree it looked better the other way .it does give the tank more depth and seems to have better coverage .I think I'll put it backin the next day or 2 I don't know how to do videos? I just hated the dull spot in the middle ... But if I do it again I'll button it up tighter in the middle ... The center of my tank is like the centerpiece hard to explain

My hidden agenda was to see your tank. Pics will work. LOL
Have the front fixtures and rear fixtures raised a little to face each other.
Front to back, blue, actinic, blue, purple, blue, coral, actinic, blue, coral, blue, purple, blue, coral, blue, actinic, blue. This is just a suggestion.

I remounted the lights the long way and it looks way better I pulled the fixtures in closer touching to fill in that spot I was talking about ..... In a pro ati hanger now done it so many times already!!! The only thing that's gonna be a pain is changeling out the bulbs I will have to pull the fixtures down or loosen them to get bulb out due to the canopy if mo reads this how do u swap out lights in your pics looks like u have a canopy as well?

Hi Brent.

I can stand next to my tank. The side fixtures I tilt towards me.
The middle fixtures I can slide out behind the the tank....

They aren't in a canopy, the tank / lights/ sump are all in a different room. The front pane is walled off.. You can see it all on my tank thread.

How high should I have the fixtures over the water? My tank is 24" deep .... Right now I have them at about 8.5" from the water line maybe 9?

Most have them closer, like 5". I'm like 3".
Closer would be better but not a biggy. Just make sure you get the coverage you need. I guess the closer you have them the hotter your water...
Did you get the dusk/dawn figured out?

I have my 8 bulb 7" from top of tank. This leaves the fixture about 8" from surface of water. Great PAR from sand to top of rock work.

Thanks for the replys I moved the fixtures down to about 6" my only prob is I have so much current I don't want the fixtures getting sprayed with salt water .... Otherwise I would have hem 2" off the surface :)

I'm running 6 radium 3 400 3 250 on a 500 gallon I've always admired tanks and the way t5 look exp... Ati my question is u guys think it would be a wate of time or not be better? Also my electric bill is crazy I'm curious if the t5 would help that as well ....I basically asking if it would be pointless or a noticeable better change?

i'm switching my 2 400 watt mh+12 bulb t5 to just 12bulb t5 today I'll let you know how it goes

BrentH
03/09/2015, 08:52 PM
I'm loving the t5 change so far ..... Another question is how long do most of you guys run your t5s?? I'm seeing some as long as 10hours and the 2 bulbs 12

Another I flipped the fixtures around so the hot air goes out the opposite side not where they touch

No more than 12 hours and min 4. I was talking with LFS that they have done testing of 4 hours on and 4 hours off for max growth.
I have my leds on for 11, 2 t5 for 9 and other 2 t5 for 6.
Are the fixtures setup with 2 switches, each 4 bulbs?
I would do 11 and 6 hours, all opinion...I try to save some $.

There's 2 bulbs on each fixture that are controlled seperate with a diff plug I run those 8.5 hours and the all of them for 7.5 I'm noticing some of my ACROS changing colors that I never saw with metal hilides lighter in color or pigment ... I'm happy with that

Yea your going to see them change color some. If they become dull then I'd suggest adding more coral plus.

BrentH

Thanks for the replys the reason I'm asking is I would like to have the lights on longer then I used to with metal hilides for obvious reason viewing the tank:) how do u like the 50/50 blue plus and corsl plus?

8.5 hours is pretty short. You could bump it up some.
