Potassium permanganate, otherwise known as KMnO4, is a chemical oxidising agent that is commonly used to purify and sanitise fish ponds and drinking water. Potassium permanganate can come in crystal or powder form, but it needs to be mixed with water before use in order to reduce its toxicity. When properly diluted, potassium permanganate is used to improve the quality of water by reducing organic matter and levelling off fish infections. It is also used in combination with water to clean off food and treat infections.

Instructions

  1. 1

    Use potassium permanganate to purify odours caused by organic matter. This compound has properties known to disinfect the impurities in drinking water. Potassium permanganate cannot be used in its purest form as it can be toxic and harmful if digested.

  2. 2

    Potassium permanganate oxidises iron and magnesium found in contaminated or murky bodies of water. Therefore, use potassium permanganate to purify harmful levels of dark metal so that it can reduce rusting in water pipes and maintain the the plumbing in underground water sewage systems.

  3. 3

    Use a properly diluted potassium permanganate to treat fish population. A well diluted potassium permanganate is effective in treating fish pathogens and infections as well as being able to kill off parasites that can have a negative impact on marine population. Water volume is extremely important in order to achieve a biological effective treatment. Overestimation can adversely affect fish.

  4. 4

    Dissolve potassium permanganate in warm water to dilute it. Treat skin problems like eczema, dermatitis, and hand and feet fungal infections. Use only in moderation. With heavily diluted in water, potassium permanganate's antiseptic properties may treat vulvovaginitis, vaginal thrush, and urine infections.

  5. 5

    Clean fresh vegetables and fruits thoroughly by using diluted potassium permanganate with water to prevent cholera and other water-borne diseases.

Tips and warnings

  • Use extreme caution when uses potassium permanganate on foods and in water. Its pure form can be harmful if digested.
  • Keep potassium permanganate away from concentrated sulphuric acid because it can cause an explosive reaction.
  • Estimate water volume accurately when using in ponds or other bodies of water where marine life reside. Evenly disperse the chemicals to prevent hot spots, or areas of the pond with excessive amounts of chemical.
  • Frequent treatment of potassium permanganate can harm fish. Wait at least four days before repeating treatment.
