Kordon Methylene Blue 4OZ

 Methylene Blue is effective against superficial fungal infections of fish. Methylene Blue is also effective in protecting newly laid fish eggs from being infected by fungus or bacteria, which is useful when artificially hatching. As a secondary use, it is effective against some external protozoans, including Ichthyophthirius (Ick), Chilodonella and Costia. Methylene Blue is very effective when used as part of a bath for treatment of ammonia, nitrite and cyanide poisoning, as well as for topical and internal treatment of injured or sick fish as a first response.
