Aquatica Basics African KH Buffer 250g bag

African KH is a phosphate free buffer designed for the fish from the Great Rift Lakes of Africa. It raises carbonate hardness by around 9dKH and stabilises pH to over 8.0, stopping pH fluctuation to create pH stability and reducing stress on fish. Add 1 level teaspoon to 20 litres of water to raise carbonate hardness by approximately 9DKH or 140ppm, and stabilise pH to over 8.0.
