Kusuri Potassium Permanganate

Can be used as a general disinfectant for ponds and equipment and for the effective treatment of parasites such as Trichodina and Costia etc.


Maximum Dosage: 6.8g per 1000 gallons (4546 Litres).

DO NOT OVERDOSE. Over dosing can cause fish fatalities.

Directions For Use:

Switch off UV steriliser until course of treatment is complete. Ensure pouch remains sealed after each use. When pond water is above 18°C, add more oxygen to the pond as Potassium Permanganate chemically strips oxygen from the water. If you have gill flukes, treat with Fluke-M or Fluke-P first to prevent fish losses, followed by a treatment of Potassium Permanganate for Trichodina or Costia. Do not use below 10°C.

Measure the correct dose and place in a bucket of hot water. Aerate for 20 minutes then disperse solution evenly around the pond over a half hour period. Potassium Permanganate will turn the water purple. After a while, the treatment will begin to be absorbed and the pond will begin to turn a brown colour. The water will need to be a vibrant purple for the whole duration of the treatment so re-dose as required to achieve a total of 4 hours of purple coloured water. For most effective use, top up with treatment just before the water turns from purple to brown. Ensure to monitor your Koi for the duration of the treatment. At the end of a course of treatment use Hydrogen Peroxide to reoxygenate and help clear the water. In warmer water, if you see the fish struggling during a dose of Potassium Permanganate, Kusuri recommend using Hydrogen Peroxide to reoxygenate and assist in neutralising the Potassium Permanganate.
