I have some day light bulbs on my tank (2 48inch) and my tank just isnt very bright. the main deal is that the light sits about 4-5 inches from the top of the tank. This is do to the canopy being the same length of the light strip. What should i do so the tank is brighter? Also I have some fishing lights (green flourescent tube you stick in the water) would it hurt to drop one in for the night time?
