Native KH Buffer 7.5 is ideal for Australian and New Guinea native fishes, many of which come from alkaline fresh water or brackish water conditions. It increases the KH (carbonate hardness) of water and stabilises pH, reducing fish stress and contributing to the good health and longer life of your fish. 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 and stabilise pH to around 7.5.
