Brightwell Aquatics Alkalin 8.3 Liquid KH buffer was specially formulated by a Marine Scientist. This liquid KH buffer is a highly effective alkalinity increasing solution (KH Buffer) helps to increase pH stability in an aquarium by raising the alkalinity.
Alkalin 8.3 Liquid KH Buffer provides a source of carbonates, which make up the majority by weight of aragonite, the mineral secreted by reef-building organisms as skeletal material.
Continued addition raises pH until 8.3 is reached, at which point the pH remains unchanged and the alkalinity alone increases. This product is free of phosphate, silicate, and organic material.
