So I'm pretty sure my fish have ich. I started dosing copper over last and the Hanna checker is reading 1.89 ppm. I noticed that my fish are still occasionally scratching, though not as much as before. I know scratching can still occur even after the ich has detached, but I'm just wondering when should the scratching stop overall?
