I just got my first sign of ich in my tank on one of my bala sharks. So we went and bought rid ich and I just treated it for the first time. So far my 3 bala sharks have it so am I supposed to do anything else besides do it everyday and then when it's about to go away do the 40 percent water change? And how long should it take for it to go away? Because i just bought my new pacu today and I dont want him to get it.
