hey guys so I just started this hobby 6 months ago and I got a blue tang 2 months ago put him in my qt tank and treated him with cupramine copper and about 2 and a half weeks later I saw the ich coming back I tested the copper and it was at the 0.5 level I made sure to keep it there but somehow the ich came back so my LFS told me to fresh water dip the blue tang for 4 minuets and dip in in hydroplex right after for 11 minuets so I did and put him in the main Display that was maybe a month ago and blue tang has been doing great in the main display so I recently just got a yellow tang yesterday and put him in my QT thank and noticed that he is scraping up against the PVC pipe in the tank so my question is should I just do the freshwater dip and skip the copper since it didn’t work the first time or should I give the copper a second chance
