My only concern with the moonlights was that the corals were not closing at night like they did before the moonlights. I became concerned that not getting any down time, or rest state, would be possibly harmful in the long run so I quit using them. Is this off the wall?
I run mine for 2 hours (til midnight) after the actinics go out. They get a little down time when the clouds are out or the moon phase is new in the ocean. I have run mine for 11 1/2 months now and no ill effects that I can see.
