actually the light im currently using in the temporary tank is just two screw in 50/50 bulbs, 1 20W and 1 10W when he gets moved to his next tank though he is going to be getting the 36" dual T5 fixture from coralife, now that i see it has all that blue i dont think it will be too bad, i still think it will be active it will just stay in the rock work more, and im going to order mine online because i cant find any place around here with good things for my aquairums without paying way too much money
