Reefbreeders/(Evergrow OEM) Fixtures D120/IT20** series

Let me throw up a quick pic, it as close to a cube tank as you could get without having every side the same legnth it's not a long 18"/24"width (front to back) tank.
Whole top:

Nice tank! I think I would still go with (3) 24" fixtures after seeing the pictures... based on my last response. I think your only other option would be to go with (4) 16" fixtures, mounted front-to-back, 2 on each side of the brace @ 6" apart (side-by-side) and 0" apart (front-to-back)...

6"+16" + 6" + 16"+6" = 50" x 20"
6"+16" + 6" + 16"+6" = 50" x 20"

This would give you your 50" of spread (length) without being above the center brace, and 40" of spread (width).

I just realized my math is off... basing your length on 50" rather than 60"...

I still like the cost savings of using (3) 24" fixtures side-by-side, but you'd have to mount them at the maximum of 12" apart rather than the 7" I posted earlier. So, (4) 24" fixtures might be best if you're concerned about hanging a fixture above the center brace...

6"+24" + 0" + 24"+6" = 60" x 20"
6"+24" + 0" + 24"+6" = 60" x 20"

Well I just thought any light directed down onto the 3" brace would be wasted. AS you can see I've been using 2 400W MH pendants per side, which supposedly cover a 24" by 24" area each. I'm not quite understanding the way your suggesting using 3 sideways. You mean left to right? If the brace wasn't there three 30"ers longways from front to back would seem ideal. And which fixtures in the 6 by 24 were you refering to again?
 
Yes, mounted side-by-side, left-to-right so the long sides of the fixtures are going front-to-back. The light spread of the 24" fixture is roughly 36"x20". You are right... 3" of the 20" total light spread from the sides of the center fixture would be wasted. Normally, the replies are that this isn't a big deal because the other 2 fixtures on both sides would help to compensate. However, with you having to use the maximum of 12" between fixtures, you might be able to see it in this case. Would you be opposed to using 4 fixtures?
 
I'm thinking thats the only feasable option similiar to the MH pendants I now use. Two on each side. Just dont want to spend the $2,400/$2,700 it would take to out fit it with Radions. Looking for a 20K "Radium like spectrum" mimicing as close as possible the 1760/1920 Watts of light I use now. Not sure how that translates over in the LED world. I realize this is a LOT of light even for a packed SPS tank and am willing to lose some wattage but i'm able to get staggering growth when things are running optimal.
 
Ok,

I've decided I am going to get two Photon24's. I have no idea what optics to get tho. i'm really confused.:crazy1:
 
At 24 deep I'd get 120* optics. That will make sure your lights blend well enough to avoid disco effect and still be adequate for your depth.

Two suggestions: let people know your expectations as to what you want to keep (2 24" on a 150 is like 2 250 MH's at best) and more important try to find some Evergrow fixtures locally (pictures are not that allways accurate), viewing them to see if that "look" is what you want and what they are growing. Also, knowing if these LED fixtures are replacements or suplemental lights to your current lights might help people advise you.
 
I think in general people tend to "over light" their tanks. I think 2 x 250 watt MH on a 150 would be plenty. My current 80 gallon sps cube is lit by a single 175 w mh. Plenty of light if you choose your bulbs wisely.

I'm upgrading to a bigger 150gal tank. These LEDs that I'm wanting to buy from reef breeders will be the lights for the 150gal once it's finished being setup.

Currently I have a 47gal bowfront that is being lit by a 36" four bulb T5HO fixture with ATI bulbs, 39w each bulb. I currently have fish and soft corals (kenya trees, rhicodia mushrooms, red/greem mushrooms, yellow polyps, and a few zoa's.).

I would like to start doing lobos and acans.

Question: Do LED light systems as a main light source need UV lights? Why? Why not?
Click to expand...

All the graphs of how much of each color the corals use have shown that they can utilize some UV but it isn't required. Just like the fact that people have been using led fixtures that are all blue & white for the last couple of years, and the graphs show that corals like a fair amount of the 650nm red spectrum. Yet the blue & white fixtures didn't have any red leds in them.And it's possible that the 'white' leds which really cover a wide range of color spectrum, may provide some UV frequencies (and some red) as well.

All MH fixtures either use bulbs that filter out UV or have glass covers that filter out UV. So there really isn't much UV spectrum in MH fixtures either.

I think most people who put UV leds in their fixtures are looking to get more 'pop' or more 'glow' from their corals when they go for a more blue overall light. And just to be clear, the human eye can't see 'true' UV light, just the colors that are created by absorbed or reflected UV off objects (like our corals) that are under UV light.

Short answer: No, there is no need or requirement to use UV leds in a 'main source' led fixture. They don't hurt, but they may not help much either. IMHO.
 
Led does not emit UV light at all from what I understand.
T5, halides & even CFL bulbs put out substantial amounts of it.

Has anyone studied to see if its important to have UV? I understand that most all older fixtures didn't have UV, but even then, only a small percentage of those even showed to work. Maybe those successful tanks were by windows.
 
I got in on the March ReefBreeders group buy. I have a pair of photon24's with 90* optics (standard layout) on order....:bounce3:
 
Also in on the March group buy.

I'm sure it's in here, but any suggestion on hanging height (2xPhoton16 w/ 90* optics over a 48x18 SPS tank)? Acclimation schedule coming from T5s?
