Potassium permanganate (KP) / (KMnO4)



KP is the antidote to the koi (at low temperatures)
Potassium permanganate (KP) for treatment of almost all common parasites in a pond: Trichodina, Trichodinella, Chillodinella, Costia.

Also active against some (initial) bacterial infections.


Caution when using potassium permanganate:

• Only on the advice of a veterinarian or experience expert;
• Wear gloves. KP can cause a difficult to remove, brown discoloration.
• Beware of spillage, KP causes difficult to remove stains;
• Dangerous in case of accidental use, KP is a very irritating agent;
• Avoid eye contact, KP is able to cause permanent blindness;
• Use a safety goggle when mixing and dosing KP. Also wear mouth protection;
• Overdose irrevocably leads to the death of the entire fish population;
• KP touch all metals except stainless steel;
• Do not use in combination with other medicines (combine at your own risk). Despite our due diligence we can not accept liability if mortality occurs after using potassium permanganate.


If KP does not use:

• When the pond water is warmer than 27 degrees Celsius;
• When the fish haps to air;
• When the pond can not be adequately aerated;
• When an oxygen-deficient medication has taken place;
• If there is insufficient circulation in the pond
• When the pond contents are not accurately known;
• When water quality is incorrect (eg low GH / KH or measurable ammonia / nitrite);
• If no decolorizing fluid (hydrogen peroxide) is available;
• If you can not keep an eye on the fish during the treatment period.


For general treatment with potassium permanganate:

KP accurately weigh. Calculate the pond content and stay within 10% margin. Does the pond drain well?
Dissolve KP in a bucket of lukewarm water and divide it evenly over the pond. KP works well in cold water. The colder the water, the safer, cold water has a greater ability to dissolve oxygen.

• Clean the filter first and try to remove any dirt as much as possible.
• Add 2 grams per 1000 liters of water;
• Note the time of administration. The water should be purple from 6 o'clock in time;
• If within 6 hours the color change from purple to brown add 1 gram per 1000 liters of water;
• If the color changes within this 6 hours from purple to brown than a third time, add 1 gram per 1000 liters. The water should be kept blue for 6 hours from the listed time;
• If after three doses the water turns brown within 6 hours, stop treatment and repeat only after 2 days;
• Stop treatment after 6 hours. Change 15% water;
• Decolorize / neutralize the water with hydrogen peroxide 3%. Dosage: 52 ml per 1000 liters. This also stops treatment immediately. (so it's easy to get used to overdose immediately)


We recommend that you treat the filter, but please note that the filter will lose much of its biological effect. You can also choose to run the filter in itself, a small pump is sufficient, extra aeration is recommended. Keep in mind that if you do not treat the filter, the risk of a contamination is greater. Turn off the UV lamp during treatment. Remove any zeolite present during treatment.


By adding KP it is possible that fish go flashing, sanding or jumping. The parasites are activated by KP, which causes temporary irritation to your fish. Steering can not tolerate treatment with KP and should be removed during treatment.
