Hi All,

I've recently added a new LED to my 90 gal partial reef. There are several "programs" in it and i'm looking at doing my own but i have a scheduling question.

While this is my first reef with my FOWLR I've always had the lights on a schedule that actinic would come on about 6:30am then 10k's about 7am and be on for about an hour and then all off by 8:30am. Then the 10k's on about 5pm, actinic about 6:00pm, 10k's off about 8:00pm and actinic off about 11pm. Figuring you have regular daylight ( semi direct ) the lights don't need to be on during the day.

Am I off base here? Should the 10k's/actinic be on all day then the 10k's off around sunset and the actinic later in the evening?

Thanks,

JB

I would imagine that unless the sunlight is very direct you would want the 10000k on at least a few hours throughout the day rather than cycling it off mid day and using the sun light that reaches the tank. my understanding is that both of the corals you listed do well under moderate light, but that would be moderate aquarium lighting not moderate ambient lighting.
