BAR folks: Few days ago PBT was covered with The ICH but still look strong. For efficiency, I was planning to remove 50% water from the QT BB 120G tank and treat all the fish with copper, remove some softies too this weekend. Please see my thoughts below: • PBT this AM looks good, seemed like ICH are mostly gone. I will remove most LR with softies. • Beneficial copepods/ bristleworms aren't copper safe so I have to remove majority of LR and rearranging LR that will causing more stress. I am afraid I would do more harm than good. Should I proceed? •Note: ~15 Fish have another 90days in the QT to make it to the DT. For now this is their home, do I need to use a pskimmer? Please advise. Thank you.
