Seachem Tanganyika Buffer is designed to enhance the environment of cichlids by increasing carbonate hardness (KH), buffer capacity and pH. It buffers to a pH of 9.0 to 9.4 and will not affect general hardness (GH). For optimum replication of the Tanganyika Lake environment use with Cichlid Lake Salt andNutridiet Cichlid Flakes. To obtain a lower pH than use Malawi/Victoria Buffer either alone or in combination with Tanganyika Buffer.
