Ok so I finally found a metal halide system. It's a dual ballast for 2 250 w mogul base and a reflector with 2 mogul bases. Picked it up off kijiji. The ballast is a cool touch ballast. Guy had it running on a 90 gallon. I touched the ballast to see how hot and it wasn't At all. My question is, the reflector is prob just under 48" long with two bulbs evenly spaced. Will this be enough light for a 6 foot 135 gallon tank that is 24" deep? I'm gonna supplement with two actinics. How high should I hang it?
