Is it possible to keep Acro's under non-halide lighting? I know the watts per gallon formula is not gospel anymore, but why couldn't it be done with the correct wattage and spectrum of Vho and fluorescent? On my 75 I have one 4x56 and a second 2x96 watt fixtures. In places my rock work comes within 6 inches of the lighting, how could this be inadequate. I think it can be done, so I bought a small acro frag to give it a go! More to follow... By the way my water parameters are dead on.
