I wanted to take out some corals from my tank because it has ich in it. I was going to give the corals to my brother-in-law for safe keeping while I treated the fish w/ hyposalinity. Do I need to bathe the corals before placing them in his tank so as to not spread ich? What would be the best method for this? I'm usually good at googling for answers like this, but I'm coming up short right now. Thanks.
