Yeah, the trick to it all is to have those fish that were in hypo stay in a QT tank at normal salinity for a month. Let the "possible" ich survivors a chance to show up on the fish again. If it does, back to hypo for another treatment.. it sucks but it has to be done.

Yeah I did not do that part. I thought after the 8 weeks there was no way any ich could have survived. But I was wrong.

Well today there is no signs of ich at all...just means I can't see it of course...I know its still there. So I am going to wait it out still and see if they fight it off again. I think I will hold off on QT until I see the first sign of stress or discomfort. Then I will decide what to do. Still may try to switch to freshwater I think.
