African KH is a phosphate free buffer designed for fish from the Great Rift Lakes of Africa. It raises KH (carbonate hardness) by adding minerals which are often missing from tap water and rainwater and stabilises pH to over 8.0, stopping pH fluctuation to create pH stability and reducing stress on fish.
Directions: 1 teaspoon to 20 litres of water will raise the KH by approximately 8dKH or 140ppm and balance pH to over 8.0. For best results, use in conjunction with Basics African GH Conditioner.
