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.
