Can you answer one more question please, prior to me starting copper power which Im in 17 th day, prior to this I used formalin for 14 days, which cleared it up then it came back so I did 5 days again of formalin and right after that the copper treatment. I also got rid of the fish who I believe to be the main cause (character) to the ongoing problem ( bat fish). So my question is is 17 days instead of going full 30. Everyone seems to be doing good no signs of ick (2 wks) since I gave the bat fish away. Sorry to be a pest and Thanks
Also it fish only display tank.
