I’m on day 5 of QT and got to 2 ppm with Coppersafe. Fish (2 clowns and blenny) are happy and ammonia is in check. i don’t plan to do a water change for duration of QT and was wondering if copper level will slowly fade or it will stay at 2. Only thing I’m adding to tank rn is food and a little BioSpira each day. May need to top off but would do so with 2 ppm copper in RODI...
