    What is the dimensions of the tank bud?
    If I was going 4*T5's in the coloration you have chosen, this would be my choice :
    3 * 12000K
    1 * 20000K
    If you going to go with 2 blue bulbs and 2 12K bulbs, the tank is going to look too blue. It might look good, but will not really promote alot of growth.

    Depending on the depth of the tank, four bulbs may not be enough especially for SPS's. I would personally add another two bulbs so you have four white and two blue.

    I would say you could get away with 4 bulbs depending on tank width and depth. I dont like a blue tank, so I would have gone 4x 12000K or 1x 20000K and 3x 10000/12000K

    Gotta ask what kinda bulbs u will b using as this makes a huge difference. 4 ati will b more than enough for all softies, lps and maybe some easy sps high up but 4 boyu's wont.
