settin up a new 75 gallon discus tank, I have a shoplight that I am using to provide lighting, for bulbs I have 2 general use lights on the tank right now I am thinking of switching to a GE AquaRays bulb and a actinic blue bulb that are on for about 2 hrs in the mornin and about 6 in the evening with a smaller 24" bulb on during the day. How does this sound? any suggestions about other bulbs or combinations of bulbs to use
