Potassium Permanganate Solution is effective against external fish infections from fungi, bacteria and parasites, Trichodinia, Costia, Chilodonella and Flukes. It also improves water quality and clarity by clearing cloudy water of organics. Potassium Permanganate is a strong oxidizer.
Application Instructions To improve water clarity, dose at 2ppm (each ounce treats 375 gallons). To treat parasites and bacteria, dose at 4ppm (each ounce treats 188 gallons). Treat in the morning, and increase circulation and aeration during treatment. Wear protective gloves, and mix well into a gallon of water to distribute evenly around the pond. Water should maintain a pink hue for at least 6 hours. Repeat dose if pink color disappears within 45 minutes. Repeat at half dose of 1ppm (1oz treating 750 gallons) if pink color disappears after 1-2 hours.
Cautions Stop active treatment immediately if fish show signs of distress. Product should be neutralized if it remains active for 8 hours or more.
