Fritz Maracyn® Oxy is a fast-acting treatment for true fungal infections on fish and fish eggs, as well as certain bacterial diseases. Maracyn Oxy works by slowly releasing a stabilized oxygen-chlorine compound that targets a broad range of tropical fish diseases, including both gram-negative and gram-positive bacterial infections.
Fungal infections look like white cotton tufts, similar to the mold you’d see on fruit or bread, but white rather than black or green. Infections typically appear at wound sites or areas recently damaged by parasites, making them secondary infections that follow an initial injury or illness. Because of this, they can be stubborn to treat without a targeted remedy.
Maracyn Oxy is formulated specifically for these cases, providing effective relief when used as directed.
