I’m currently treating my fish for velvet/ich with Kordon Copper-Aid. I was wondering if the medication will kill all the benefical bacteria in the tank. If so, should I feed less while I’m medicating? I will monitor the perameters as closely as I can. I am also using aquarium salt idk if that will affect the answer to my questions. If the medicine kills the bacteria, should I just do water changes more often while medicating and wait till after I done medicating to add some sort of bacteria supplement? Any advice is greatly appreciated.
