I just got a new copperband a few days ago, and put him in a q-tank when i got him. He's been being treated with copper the last 4 days...however, the nitrates in the tank soared. I don't know what happened because I took the water from the main tank, and today the levels were right on when I tested. The levels in the q-tank are currently, ammnia - 1, nitrite - .25, and nitrate 10(ppm). I did a quick water change when I found them high, and this is still the levels they are at. Is it better to leave him and continue with changes, or should I put him in the main tank to ensure he doesn't die from the high levels and maybe risk the other fish getting a disease if he isn't totally healthy? Please help!
