Hi quick question with this method. When you transfer the fish after the 14 day mark assuming you've kept the copper level at therapeutic (.4-.5) levels during the whole 14 days, how long should you leave the fish in the clean sterile QT for observation? Would 1 week be sufficient? I'm dealing with 2 Acanthurus tangs so being ich magents and lets say for whatever reason the 14 days didn't work they should show signs within that 1 week observation time of no copper right?
