Some people will never learn. cleaner shrimp and mella green will do nothing for Ich.
Given that many fish with Ich show no sign at all, I do wonder about the QT process and the way people think it is %100 successful. The Ich is pretty hard to see when on the gills.
If it wasn't for the tell tale fish such as surgeons and blennies, the Ich can go largely unnoticed even after QT.
Peroxide dips are another option that is still being tested. The fish can handle the peroxide although the peroxide is not reefsafe.
