6 T5's will be fine and you really wont need to stagger them.

You can only fit 8 lamps over a 24" space. If you order through Reefgeek you can upgrade to IC reflectors for 2 bux a lamp.

The ATI powermodul can fit up to 10 bulbs in a 20" deep unit.
The fauna-marin can do 6 bulbs in 11" or 4 bulbs in 8". So you could use a 6 and a 4, for a total of 10 bulbs, in a 19" space.

Should look like a 10K halide, perhaps a little more blue to it.

a 4x54 watt Ice Cap retrofit puts more light to the bottom than a lot of 250 watt halides. A good system with Lumenarcs/Lumnmax reflectors will best the T5's but not mid range systems.

Then you might as well go with 2x GE 6500K and 2x ATI blue+. That would be the brightest combo that would grow corals better than what you are listing. More output and better spectrum spread I mean. The only thing that it might lack is some actinic, in which case, an extra G-man true actinic03 could be used to step in for one of the blue+ or 6500K bulbs (if it subs for a 6500K, the tank will look more 14,000Kish, if you use it to sub for a blue+, it will look more 10,000Kish).

I have numbers for 6x39wattT5 vs 250wattDE/HQI-M80 ballast.
Beyond numbers, I can tell you that the corals like the 6x39wattT5 better.

I'd take the Aquablue over the GE for growth. All that green light the GE is putting out does little or nothing for coral growth.

HOLY CRAP!!!...There were at least 4 splits in this thread!...Anywho....
I've read too much and I just need some guidance. I am setting up a 75g. It will have a canopy. I like the price of the Finnex 47" 6x54w. I understand that I can do the individual reflector mod to make it better. I am worried about heat and don't want to have to buy a chiller. Will this work for me or should I go a different direction. I would love to be able to do sps and a clam. Concerned with heat first, price second, but won't buy junk.
BTW....I am already boycotting Citgo!!...

Any opinions on what brand of SA or Actinic 03 T5HO bulb to use when overdriving with ICECap? The dealer who sold me my icecap ballast and reflectors says to not overdrive super actinic. But my G-Man aquablue and blue plus overdriven bulbs perform so well that that I want to try for the extra performance from the SA as well.
I have always had good results with G-Man bulbs, but hear a lot of recomendations for the new UVL SA.
Anybody have experience with both, and assuming that they are properly cooled, how long should they last? Thanks

Grim,
If the GE looks more like the aquablue now more than ever, then isnt it just a low cost alternative? I didnt think it had alot of green anymore, but even so...
Also, the idea that green light doesnt do much is true of land-based plants... to them only red light is used for budding, and blue light is for growth. But for corals, it seems that various species are able to use the full range of spectra...

If you are mounting the lights in a canopy you really should stick with retros, they have moisture resistant endcaps. The Finnex doesn't

Ahh but you're talking about fluorescence there, not growth. Green light will cause some red fluorescence but not much.
Steve Tyree has a DVD out that goes through some really cool stuff about what the corals use the light for. It's call Biological Light Requirements of Photosynthetic Corals. http://www.dynamicecomorphology.com/

Also, to me the GE just looks pure white, the Giesemann Midday should be a much better lamps with higher peaks in the red and blue spectrum the coral use.
