I'm dealing with my first Ich outbreak in my main tank I was told by my LFS to set up a QT tank quickly. I got a 20 Gal tank, heater, and an inexpensive over the side filter (did not use carbon) and am using CopperSafe (1 tsp. per 4 gallons). I put about 30 - 40 of my bio balls from the main tank in the QT tank and water from my main tank to fill up the QT tank, and then put the fish in (5 small). In less than one day my amonia spiked off the charts. I only had enough water to do a 5 gal. water change and today I am going to do another 10 gal. water change. My question is am I going to have to do 10 gallon changes everyday for three weeks?????? or should this just be an initial problem with setting up a QT tank or does the Copper cause unreliable readings.
