My display tank now has velvet. I have lost 3 fish already and be other is hiding/missing. I have set up a QT tank immediately but I have no transferable media other than Live Rock. I have Cupramine ready to start treating and plan on freshwater dipping the badly affected fish before placing in the QT. My issue is the QT isn’t cycled, so do I add Colony or Dr Tim’s, or do I just use the Seachem Ammonia plate as a warning and carry out daily water changes until the 10 days of treatment are over? I have some Live rock in the sump I could use and discard but I believe the live rock will absorb the copper and take it out of the required parameters??
