So I've recently been cycling a 35 gallon tank for two fancy goldfish. It has been cycling for two weeks. I've used the necessary items such as stress coat and stress zyme. it has a filter and an aerator. So my local fish retailer was a little dry on goldfish so I foolishly went to another shop to purchase two fancy goldfish. A black moor and a fantail. Upon releasing them into the tank I noticed the black moor had white spots on its body, ich. This is where I'm having problems. Im using King British WS3 to try and kill the ich. The spots went away for a while but came back. I then set up a ten gallon quarantine tank for the goldfish where they are being treated (I know ten gallon isn't near suffice but it was all I had). I then placed a heater in the main tank, cranked it up to 86F and I'm continuing to use the WS3. heres the help I need. when will it be safe to put the fish back into the tank? How long will it take for the tank to be cleansed from ich? And if the fish are put back into the tank at a normal cool temperature but a couple of spots are still lingering on them, will the ich break loose again? Thanks. additional details. 0 ammonia Small bit of nitrite. 0 nitrate. ph between 7 and 8.
