Ich, how long to keep display tank without fish?

[fishtacos]

Have Ich in my tank, I have no fish in it right now, just some snails and corals... How long do I need to leave it without fish to ensure that I have broken the lifecycle?

6 Weeks. Any sooner than that and you will be taking a big risk.
