This is a reef tank I got that was established well before I got it. I am new to reefing and revived all of the corals inside this tank back from death. But one thing I thought was off is the staggering amount of snails that are in there. Is there such a thing as too many? Should I rehome them? Would this be messing with my levels in the tank? Would love some input. (Every tiny black spec is a snail)
