On November 10th I started the heat/salt treatment for ich in my 25 gallon tank. After a couple of days of cysts appearing (at quite a fast rate, I might add), by the 14th, there were no more cysts on my fish (that I could see). I've kept the temp high and salt in the tank since then (its been just over 10 days since the last visible cyst). Can I now gradually reduce the temp to 78ish and reduce the salt gradually through water changes? I believe I read somewhere to continue the temp/salt treatment for 10 days past the last sign of ich on the fish. Does this sound right? Thanks in advance for any response.
