Ok, just got this 55 but the problems aptaisa, I have four large peppermint shrimp that don't seem to be touching the stuff, should i get some pickling lime at walmart, will it affect the tank, and where to you get a needle to inject it with or do you use a turkey baster?
Any help please as I would love to add more corals but need to get these beasts under control asap, there are about 50 in the tank including one large sucker.
