I am building a canopy for my 50G tank (will have 2 x 96w CF lamps, which will be on timers and on at different times).
My question: I am trying to decide how high to build the canopy. I've read/been given conflicting information and cannot decide how high above the water the lamps (bulbs) should be. I wouldn't mind having the lights 4 or so inches above the water, so I'll get fewer water spots on the reflectors. Any advice would be appreciated.
