I thought I kept the store bought fish in isolation for long enough. Well I was wrong. Now I have ICH in my tank. This really sucks. Since moving the entire colony into a hospital tank for two weeks is not really an option, I've begun treating (with heat and salt) directly in my AP system. I'm very worried that I'm going to kill off my bacteria, worms, and plants. I wonder if the fish are worth it? I could just go get more and start all over. hummm?
