After almost 2 weeks of QT and noticing nothing, I put Chucky in a holding area in my 10 gal.DT...While he was in there and more visible, I noticed a small spot below his mouth...thinking it may be ich, I returned him to his QT and began to treat him with Cupramine...only then did I realize that nitrates had gone to 20ppm in the QT...so...I changed water, about 30% and now I'm not sure what to do since I had started the copper and than took most of it out...this is my first experience using copper...I'd love some advise here...what to do...what to do...come on R2R people...lets help Chucky...
