African KH Buffer plus Potassium 1kg

Phosphate free. African KH Buffer helps emulate the waters from the Great Lakes of Africa, raising carbonate hardness by around 9dKH and locking up the pH at around 7.8 to 8.5, stopping pH fluctuation to create pH stability and reducing stress on fish.  It also contains minerals that assist with fish fertility and egg production.

Add 1 teaspoon to 20 litres of water to raise carbonate hardness by approximately 12KH or 214ppm, and stabilise pH to about  8.5
