Hello friends, I just want to share my story about battling with ich, marive velvet and bacterial infections on my 120 gallon bare bottom FOWLR tank. A couple weeks ago my fishes contracted these parasites and BI. So I humbly asked this forum for help. People like @Humble fish, @melypr1985 and others help me and gave me an idea which treatment is best for my situation. So here are the fishes that contracted Ich, MVand BI. French angel Harlequin tusk Purple tang Powder brown tang So after the suggested treatments like Copper, Hyposalinity and Tank transfer. I decided to go with Copper treatment and prazipro on my display tank since I don't have any inverts. Now after a week spots are gone and fin rots and bacterial infections went away. I still have 3 more weeks for my copper treatment and I just dosed my round 2 for prozipro today. Here are some before and after photos of the infected fishes. I have bought Zyme 9 from fritz aquatics because they told me to put these bacteria so I can control the ammonia in the tank. I just want to share my experience with you guys. I will update you guys when I'm totally done with my copper treatment.
