Today I went to an old friends house and seen that he some how had all of my old live rock and coral that I had for my saltwater tank a few years back. So I took it back and now am thinking about using it for my cichlid tank. Here's the catch, the reason I broke my saltwater tank down way back then was because it had really horrible catastrophic ick. I talked to a guy at the LPS and he said that ick can stay in substrate for up to 7 years. So here's my question, how should I clean the live rock (which is dead now) and coral to make sure that there will be no ick incident?
