i know that the MH should be mounted between 6-8" above the water. how about my copact florescent bulbs? they're actinic do they make a difference?

I've always gone between 3-5" from the water for VHO, and PC. If your using Halides, you'll want the pcs about the same height as the halide to ensure an even distribution of light from the halide.
