Kusuri Potassium Permanganate is another popular powdered chemical for various applications.A good disinfectant for ponds and nets. Excellent for the eradication of Trichodina & Costia, and other parasites. It will discolour water for up to 7 days, and can be used down to 10°C (50°F). At higher temperatures Potassium Permanganate removes oxygen from pond water, it is advisable to keep an air stone running and add more air if possible. Kusuri Hydrogen Peroxide 6% can be used to increase the oxygen levels in pond water and also remove the discolouration from the pond water after a course of Kusuri Potassium Permanganate has oxidized from pink to brown. From 14th of January 2013 it is illegal to send Potassium Permanganate via the Post Office as it is classified as an oxidising agent. This will incur our small order carriage charge if the order is under £35 because of the specialist courier we use. Kusuri recommend NOT using Potassium Permanganate with salt. Please ensure that you read, understand and follow, all Health and Safety guidelines on the packet. Please do not eat, drink or smoke whilst handling chemicals. Wear disposable vinyl or latex gloves and appropriate eye protection.

Dosage: 6.8g per 1000 gallons (4546 Litres) of pond water. DO NOT OVERDOSE. Over dosing can cause fish fatalities

Do not use below 10°C (50°F).

Switch off UV steriliser until course of treatment is complete. Ensure pouch remains sealed after each use. 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 one hour period. Do not use below 10°C. Potassium Permanganate will turn the water purple. Re-dose as required to achieve a minimum total of 15 hours of purple coloured water. When pond water is above 18°C, add more oxygen to the pond as Potassium Permanganate 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 Coastia. At the end of a course of treatment use Kusuri 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 Kusuri Hydrogen Peroxide to reoxygenate and assist in neutralising the Potassium Permanganate.
