Take it from someone who is treaing Ich as we speak......I'm into week 5 of QT land for my tangs (4 of them in a 20g) and they are doing well. As many posts suggested, no LR
, or anything pourus (sp?) in the tank. I feed them every 2-3 days and I change 5-7 gallons of water every other day. I also chucked my bio wheel and added a sponge that was in my main tank's sump for a couple of weeks. It seems to help with the Ammonia levels.
It seems like a lot at first, but my WC
's take about 10 minutes and I've left my main tank fallow during this whole time. I do have inverts in there with 2 cleaner shrimp, so I'm hoping in 3 more weeks that I'll be able to add my fish back to the main tank.
I've treated the QT with copper for the first month and now I'm going to try Hypo for the next 3 weeks. Definately don't want to do both, as the PH will drop too low too quick. The Ich has removed itself from my tangs and they are very alive and looking well now.
I did a couple of FW
dips in between my changes (3 dips total, 3 minutes each fish) and it has seemed to help, but take that with a grain of salt. Some say it works and others don't.
Good luck with the Ich and keep us posted as to how things are going with it.
