What is the proper distance to mount the following light source from the water surface:
Four bulb VHO Champion lighting flourescent fixture, fan cooled, (4 x 110 watts), on a tank that is 4' long by 2' wide by 22" deep. There is four inches of gravel and a 1" top of glass edge to water surface distance.
I've heard everything from 1" to 8". Suggestions?
