The life cycle of the parasite is about 6 weeks. leaving your tank fallow for about 8 weeks is a good way to ensure the parasite does not survive. Moat importantly, begin to QT all new arrivals to prevent the re-introduction of it into your main. Kick Ich is a waste of money and it is never a god idea to treat the main, regardless of claims that is will not effect it. I suggest a couple large water changes and some fresh
GAC to clean the tank water. Good luck.
