Blue clove polyps took over my tank. I don't want to kill the live rock because it's been going for close to 2 years. I have all the rock in it's own tank now with no corals besides the blue clove polyps. Anyone know of a fish or invert that will eat those guys up? I searched all over Google and can't find a straight answer. Also, what if I went dark with the tank? How long should I keep the lights off? Thanks!
