My understanding is that 8-10 hours a day is a good amount of time to have the lights on your reef tank. My question is, can that time be split into two segments? I.e. lights on for 4 hours, then off for 5 hours then back on again for 4-6 hours? Is this a problem? Will it mess up the corals and their daily cycles?
I've always just left the lights on for one long period, but a split schedule would allow me to enjoy the reef more with the lights on.
