I usually turn the lights out in the refugium at night when the I go to bed.ANEMONEBUFF":381kwktn said:The only problem is that the goby will eat many of the critters that you want in the refugium. I do not think that he will wipe out the whole cash of pods, but he will deplete the population. The refugium will be fine with the macro algae for nutrient removal.
Are you going to do reverse lighting?
24/7 lighting will not be good for the fish IMO.
