Hi, I have an oscar with fin rot and was wondering if this was an effective treatment: I moved the oscar to a 10 gallon hospital tank, then for the first week I've added salt, maracyn, and maracyn 2, then the second week I will use just salt, and then the third week nothing. Each day I will do a 50% water change until the 3 weeks are over. Does this sound like an effective treatment?
