Kordon Methylene Blue
Kordon Methylene Blue is a classic, time-tested remedy with two main uses: treating fungal infections and supporting fish suffering from oxygen-transport problems, including nitrite or cyanide poisoning (methylene blue helps restore the blood's ability to carry oxygen). It's also a long-standing favorite for treating fish eggs against fungus, and as a gentle dip or bath for stressed or suffocating fish.
Good to Know: The one thing everyone learns about methylene blue is that it stains — vividly and persistently — silicone, ornaments, and just about anything porous, so it's best used in a bare hospital tank or a separate dip container rather than your display. It also harms the biofilter and is not plant- or invertebrate-friendly, so it's a quarantine/dip tool, not a main-tank treatment.
For egg hatching, emergency oxygen support, and antifungal dips, it remains an inexpensive essential that's well worth keeping on the shelf.
Dosing Guidelines: Use per the label as a tank treatment, dip, or bath; for eggs and emergencies, follow the bath/dip directions. Always treat outside your display to avoid staining, remove carbon while treating, and keep it away from plants and inverts.
