Potassium Permangante - 1/4 lb

Potassium permanganate is a very strong oxidizer which works well for treating a wide range of fish diseases, but must be used with great care.

Potassium is a granular powder which turns the water purple during it's effect. It oxidizes organic material, including the surfaces of bacterial sores (ulcers) and the parasites that cause them. Once it's spent it's energy on the pond and parasites, the potassium turns amber or brown and can be removed with a water change or with hydrogen peroxide (3% USP)

Directions For Use:

Potassium permanganate is applied at the rate of one gram per one hundred gallons or one level teaspoonful per six hundred gallons. E.g. 8 level teaspoonfuls in a 4800 gallon pond.Once the potassium has turned Amber or brown, it can be removed it with a water change, dechlorinator or with Hydrogen Peroxide (3% USP) - In case of over dosage or untoward reaction to the potassium, you should be aware that it is INSTANTLY de-activated by De-Chlor (Sodium thiosulfate) or also by Hydrogen peroxide. The neutralizing effects may last three to four DAYS afterwards, inhibiting subsequent treatments.

The presence of large amounts of organic debris, uneaten food, dead fish, leaves, dead plants will cause the potassium to spend it's energy on oxidizing the organics, not on the parasites or ulcers.
