OK, I get a high nitrite, and ammonia reading for my qt tank in which I'm treating with cupramine. It is a 20 gallon tank. I then do a water change of 12-13gallons, and retest. The levels are still high. Chemically I dont understand how this can be. Please advise this newb on the chemical truths of water changes.
