Potassium Permanganate (PP) Calculator
Enter your pond volume in gallons and your target dose in ppm. This calculator will estimate how many grams and ounces of potassium permanganate powder you need.
Typical pond treatments are often in the 1.5–4.0 ppm range. Always follow your chosen protocol.
Notes: This calculator assumes pure potassium permanganate and standard conversions (1 US gallon ≈ 3.785 L, 1 ppm ≈ 1 mg/L, 1 oz ≈ 28.35 g). Always double-check critical treatments and monitor fish closely.
