Lighting Help

[Deepsea2005]

Hello,

I'm setting up a cube tank (36"x36"x 24" high).
This will be a SPS tank.
I will use IceCap 660 ballasts.

Can you tell me how many 39w T5s do I need to light it?

Can you show me the best bulbs combination, too?

Thanks,

i believe they say 6 for 18 wide tank so its gonna be 10 or 12
