Thanks Tom
Lenny-
The end SEIO's are 2600's and the middle SEIO's are 800's, the return is shooting back about 1200 from the sump. So, with that I am running about 8000gph for 64X turnover. Right now I feel this is more than adequate. I had about 55X turnover in my old tank and that worked out great, I had both great coloring and growth. For lighting I went with three pfo mini pendants each firing phoenix 14k's off of pfo HQI ballasts. I really think for this tank three are needed, I think the tank is too long for two pendants. Even if two pendants are placed near the center the edges might look distracting with longer shadows. I also think painting the back black was a very good choice, the colors just are more vibrant against a black background. The tank is nice to work with beacuse it is only 18" wide, however, the two overflows do take up quite a bit of space. So, that being said plan accordingly to work arond the overflows. Not having a sump under the tank has been nice as well, working in the sump -sort of unobstructed is a good thing.
Hope any of this helps and thanks again for the great comments everyone.
