    I run mine 12 on 12 off. I find that if I leave my lights on for, say, 16 or so hours, the corals actually look stressed. They need to shut down for the night. Whether this is one of the great truths or not, it is very consistant. During the last two weeks or so, I have kept the lights on until midnight or 1AM. By that time, they do not look so good. So 12 and 12 gets my vote.
