I'am looing at a new lighting system for my 75gal. The system is a black aluminum canopy hood. It has 2 175wt. 10k metal halide bulbs and 2 96wt. 7100k blue pc flourescent bulbs. The canopy has two 4in fans built into the hood. First question would this be enough light to run sps corals in a 75 gal tank 18 inches deep ? Second question would i be able to place this canopy on to the top of the tank or would i need to hang it above the tank? Third question would i need a chiller for the tank or would the two 4in fans keep the water temp. down in the tank? Thank Tak.
