[psilentchild]

I think i have black ich.What is the best way to cure black ich in DT.It is a FOWLR.My tank is too big to try and catch fish.I would have to break down the whole tank and that not an option.Plus my fish are too big to all be put in QT.So I have to treat DT.I also have 3 cleaner shrimp.

Here is some info on it.It says use formalin so using that in a dt may be a problem although i am not sure as i have never heard of anyone using it in a dt.It says on the bottom to use hypo for fish only so maybe that will work in your situation HTH-Kieth
