So I purchased a Nano Cube 28 Gallon a few months back. I was excited that it had MH lights and the protein skimmer. Now I'm not so sure about MH, and would like some advice. I originally had my lights on for about 12 hours a day and was told that I needed to cut back immediately to about half of that. Now it gets anywhere from 5.5hrs - 7hrs a day. It seems that a lot of corals can't handle the intensity of the MH and can't be positioned near the top. The ones that can and flourish in the light seem to not like the movement up top near the pumps. Can you guys recommend some corals that will do well under intense lighting (not sure if mine are even THAT intense = 150W HQI/14K Light with German parabolic reflector.) as well as handle the movement?
