I started treating my fish over a week ago with ich-x. Once a day and I do a 20% water change prior to re-dosing the tank as directed. So far no casualties! However when I first noticed the ich, only 2-3 fish had one to two spots of ich. But now it seems like they have it everywhere. Prior to a few days ago, my clowns hadn’t had any areas and now their tails and filled with it, and my fire fish is covered in cysts. Should I attempt to do a different treatment. Ich-x was recommended by my lfs so I had gone with that one. I currently have them in a quarantine tank since my main tank is a reef tank. I was planning on leaving the main tank fishless for the next 76 days since that’s the recommendation since there’s no way of truly treating a reef tank. Any help would be great! https://share.icloud.com/photos/04mZ-49b-JkXBkS5CsPY_fJWw
