All my fish and my blue hippo tang have been in quarantine for 55 days while my display is fallow. First 30 days in coppersafe at 2.0 on api test, last 25 days with no copper, was getting ready to dose prazipro but now she has a white spot close to her eye. I have restarted the copper just in case. Only 1 spot and it's been there 3 days.
