I was wondering about that. I noticed with your deeper tank that you were going with 250's. You hear so much about light, light, light that I thought if nothing else I'd put one 400 MH in the center. I'm not going to have a SPS only tank and never will. I have one 250 now over my 65g and the SPSs do seem to be doing really good. Nice color, for the most part they're health except my purple haze over the last two week started looking like it wanted to TRN. The Hawkster helped me treat it and a few others - not sure what it is. I really don't think it's related to light. Might have to change that 400 to a 250 which I'd like better (cheaper).
We'll have to see how your tank looks and how your corals do with yours - nothing like having a test system
