So I just purchased my AI hydra and can't figure out how to set them up through the controler to turn the lights completely off for a few hrs during the night between sunrise and sun set. If anyone has these and can help I'd appreciate it. Also what would you recommend the intensity percentage and distance to set the light from the water in a 24in deep tank ive heard 1 foot above the water surface. Also is it okay to have your UV
on at night I know the UV
makes zoas and other corals pop but in a natural setting I assume there isn't UV
at night? Constant UV
won't have a negative affect eventual will it?
