Blue Hippo Tang keeps getting ich.

Hey Joe
I prefer to put an Ich infected fish in QT until the visible spots disappear, then start the clock. Minimum 4 weeks to pass the next cycle of Trophonts, then watch for another 2 weeks for signs of new infection. So in my case, it can be up to 7-8 weeks in QT.
Last time I had an issue I ended up running my tank fallow for 86 days while I treated the survivers in a Hospital tank.

Good luck bud
