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.
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.
Dosage: 6.8gms per 1000 gallons (4546 Litres) of pond water.
Directions: Measure the correct dosage for your pond. Add to a bucket of hot water and aerate for 20 miniutes to gas off any impurities. Fill a clean watering can with solution from the bucket, slowly apply to the pond over a 1 hour period. This will prevent shocking the pond with a highly concentrated dose. Kusuri Potassium Permanganate will turn the water purple. Re-dose as required to achieve a minimum of 15 hours of purple coloured water e.g., 2 hours and the pond goes brown, redose, pond goes brown after 5 hours, redose, pond goes brown after 8 hours. 2+5+8=15 hours of purple water. Kusuri recommend adding Hydrogen Peroxide 6% to re-oxygenate and clear brown pond water.
Kusuri do not recommend the use of this chemical with salt or as a dip treatment. Do not use below 10°C (50°F).
