Goldfish don’t like acid pH, so Goldfish KH Buffer raises KH (carbonate hardness) and stabilises pH at around 7.2 to 7.4pH. This stops stressful and damaging pH fluctuation and contributes to the good health and longer life of your goldfish. Contains chemically clean phosphates, which should not exacerbate algae.

Directions: 1 rounded teaspoon or 8g to 10 litres of water will raise KH by approximately 8dKH or 143ppm.
