I have a flame angel that just hit 30 days in copper power for ich. I still have a month plus of fallow time before it can go back into display. I read IO salt mix will raise ammonia and I already had trouble a few weeks ago before the new QT cycled and had to add ammonia remover. Wondering if I should just leave it in copper for another month versus doing a big water change to reduce copper but potentially causing ammonia to go up. I have a sponge from the old tank for bacteria but afraid of ammonia trouble again. Nitrite finally just dropped to near zero and ammonia has been absent since I used the remover.
