Amazon KH Buffer helps your aquarium water emulate the waters of the Amazon Basin by raising KH (carbonate hardness) without compromising the slightly acidic pH required for fish that come from this region, such as discus, tetras, Apistogramma and L-number catfish. It raises KH and locks in pH to approximately 6.5 to 6.8, stopping pH fluctuation, creating pH stability and reducing stress on fish. Contains chemically clean phosphates, which should not exacerbate algae.
Directions: 1 level teaspoon to 8 litres of water will raise KH by approximately 6dKH or 107ppm and stabilise pH to around 6.5 to 6.8.
