adding copper or any other treatment to your tank is a big no no. Never ever add any kind of treatment to your main tank. Not even ones that say reef safe on them. The reason being is that the change around the parmeters of the water with such things at metal. Your best option is to have a qaurentine tank to move fish to and treat in this tank, as to no upset the balence in your main tank. The other problem is, is that the copper ich treatment can seep into your silcone seels of your tank and stay there and slowly release back into your tank. And there is no way to fix this or stop it. Your best option now is to just wait and continue water changes and to by a copper
test kit and test your tank to see if any readinings show. Copper is highly toxic to all invertibrates and coral. I recomned waiting 3-4 months before even attempting to put any of these into your tank.
