I lost all my fish to a BAD ICH breakout in my tank. At what point will I know when it is safe too add fish again? It has been about 2 months since the last fish was in the tank.
Sorry, I hate Ich so I avoid the subject , just hinting of it makes me want to make the rounds
IIRC ~30 days at 82-84, ~40 days at 76-78.
Lately I've been experimenting with treating Ich in reef tanks via preventing secondary bacterial infections and letting the disease run its course. My results have been very encouraging. I'll have to do a post on it the next time one of my tanks becomes infected, the last tank I treated was a 300g with great results.
I'm not the expert Gresh refers to, but just to be safe I've gone by the rule of thumb of 8 weeks with no host AND no new introductions. Some folks think "no fish, no problem", this is just an invert ... however, the invert could be holding cysts that restart the clock.
