Try to get chelated copper (I.e. Copper safe) and the API test kit. Chelated copper is much easier to use.I used a copper sulphate (I think) it was the only copper treatment my fish store had and I read that it was either copper or hyposalinity to cure ich. I can remember the name but I went to 3 different stores and this was the only copper treatment. I will get the name when I'm home from work.
I used a salifert copper test kit though.
Ok so I would have to do 76 day period again? Even though the clown had ich and after the copper treatment there was no more sign of ich? The clown was back in my tank for around 12 hours and I found him dead and took him out. There were still no signs of ich on him.
I'm pretty sure the copper treatment I got said that it can be used for a 24hr copper bath when qting fish. Do u recommend this at the beginning of qt or at the end if I was going to do this? Obviously I can't leave LR in the qt when I put the copper in as it will kill all the benificial bacteria and ammonia will spike. Could I do the copper bath then run some carbon then put the LR in?
30 days is even better. Have you looked into online ordering?
