Hi Everyone,
I added the copper solution to my display tank for prevention of any parasites that may harm my fish. Now I want to add back corals. Now, I've read you have to completely change the water and remove all rocks/sand then put fresh RO saltwater back and let the tank cycle. Am I wrong? or is there a better way?
