90 gallon setup

[uncwba00]

I am setting up a 90 gallon tank. I have a canopy with 4 t5s, I would like to ability to keep SPS in the upper portion of the tank. I am just trying to get more suggestions (and more reasons) than I have gathered so far, I just like to get lots of opinions in such matters.

What 4 bulbs would people suggest for this task? IF it comes down to growth over display, please say so.
How far down the water column should I expect to be able to grow SPS with these bulb suggestions?

What acros would be the easier to keep with this bulb selection?

I do have an LPS dominate tank currently and would move some of those over for the lower depths of this tank, so this is not a starter tank.

Thanks very much everyone.

I'd say 3 Blue + and one Coral +.
My personal favorite is 50% Blue + and 50% Coral +, but in the case of only 4 bulbs, I would shoot to maximize the PAR with Blue +.

Unfortunately, 4 T5 bulbs isn't very much.. Especially if its not a higher-end fixture with nice reflectors and ballasts. Won't say it won't do the job, but don't be expecting to keep the best Acropora. I'd say SPS wise, you might be better off doing SPS such as Birdsnest or Poccilipora. You can try some Acropora, but I'd start off with cheapy or free frags to see how they do.
