I have other threads about trying to beat Ick and I went with QT and Copper. Since then I have lost a couple Damsels, 2 ClownFish, and my Koran Angel. The Nitrites got very very high and I did a huge water change. I might have caught it too late and I am thinking maybe that is why the Koran died. I have been using the Copper for a week now and day 3-4 semmed to get a little better. I could only see it slightly on the Hippo Tang. Now day 7 it is back all over the hippo tang and another Damsel .My sailfin looked like it had nothing and now it is back on him also. How long does it take copper to work? Also I was thinking about quittting the Copper and trying something else like Formalin. Is this a good idea? Can I add Quick Cure with the Copper? I hope I can save something, it is not looking good. I know you have to have the correct amount of Copper or it will hurt the fish or do nothing to the Ick. THe test kit is so vauge, is there a better kit? Please help, THanks
