I have a 55 gal tank w/2 pc 65 w + 1-48" actinic light. I have a friend who works for a electric supply shop which is going out of business. So, here's my question, is it possible to buy a MH fixture/ballast from them and use it over a fish tank. The lfs said no because it would not have enough Kelvin, but what if you used a MH bulb specific for aquariums. Anyone use a diy mh and had good results? THANKS in advance.
