My refugium is 24x24x18 deep, I have the 120watt LED on for 12 hours a day, but I am still pulling out 10 large hand full every 10 days or so. I have roughly 100 hermit crabs and snails in there of various types, the sump is crawling with pods. Is this too much algae ? Will it stop eventually ? Or over grow the refugium totally ? Will reducing the light times reduce the growth ? Of should I just turn down the intensity ? Or just keep pulling it out weekly ?
