So it's been about two weeks since I added copper safe to my 10 gallon hospital tank after my angelfish and my teardrop butterfly showed signs of ick all the fish were clear of any white spots The next day. Two days ago I did a complete water change emptying the entire hospital tank and rinsing the tank itself out with vinegar. This morning I woke up and my blue girdle angelfish has one spot on him nobody else has anything. Yet ? I don't have a copper test kit which I will get so I figured the complete water change and new dose of copper would help.
