Ok my belly crawler pike has had ich for about a week or so. I raised the temperature in the tank to 84 degrees and I have added 1 tablespoon of aquarium salt per 5 gallons of water to the tank. I have heard this is the way to go for treating ich but I have done this for a week now and it has not gone away. Is that because it only kills the free swimming ich and the ich on the fish needs to exhaust its life cycle? How long does this treatment take to get rid of the ich? Should I up the temp even more? Any advice would be appreciated.
