Phosphate free. Tanganyika KH Buffer helps your aquarium emulate the water of Lake Tanganyika. It raises KH (carbonate hardness) and stops pH fluctuation, creating pH stability and reducing stress on fish. It also contains minerals which assist with fish fertility and egg production.
Directions: 1 rounded teaspoon or 8g to 40 litres of water will raise KH by approximately 8dKH or 143ppm. 1 rounded teaspoon or 8g to 20 litres will raise KH by approximately 16dKH or 285ppm. PH will stabilise to around 8.5 to 9.5.
