water parameters are stable unfortunately I don't have a copper test kit and I can't afford one until I get paid, I dosed it according to the directions. I have used it before with great success. Do you think I should do a water change? He's in a 20 gallon long and has been in treatment since Sunday. I see no signs of stress and his color has WAY improved. I still see ick on his fins but nowhere else. I would have kept him in the dt but I was afraid my other fish would get ich. You seem very knowlagable and I appreciate the advice. Im doing the best I can unfortunately I can't test the copper level. I was planning to move him back Sunday which would be a week is this too soon?
