Kordon Methylene Blue - 4 ounces
Methylene Blue is effective against superficial fungal infections of fish. The drug may be used for the control of fungus when it is known that the fish to be treated are sensitive. Methylene Blue is safe for use for the prevention of fungal infections. As a secondary use, it is effective against some external protozoans, such as Ichthyophthirius (Ich), Chilodonella and Costia.
The therapeutic action of Methylene Blue on bacteria and other parasites is probably due to its binding with cytoplasmic structures within the cell and also its interference with oxidation reduction processes.
