I have 56g with 150w 10k MH, 2 65w Actinic, and 2 1w moonlight LEDs(Coralife Aqualite Pro)
Does the moonlight in anyway effect the lighting cycle for corals or is the wattage so low that it is a non-issue? Can I leave the moonlights on all night?
Corals: Green hammer, yellow polyps, green and purple mushrooms, green bubble, green and purple star polyps and assorted zoanthids.
Some people put moonligts on a controller type timer and use it to simulate the rising and setting of the moon. In a few cases they have had corals spawn with such an arrangement.
However, for a typical reef it's not that big an issue and you could leave moonlights on all night and it wouldn't be an issue.
