Maifanite gravel has an excellent composition. It allow to stabilize the water quality, and let you to preserve healthy breeding environment. The In addition to the silicon and acid, aluminum, iron, calcium, Maifanite contains such elements as potassium. Among noteworthy potassium known as contained in the potash feldspar of pink. Little by little it's melting in breeding water into Li ions, whose absorption used as an essential element of killifish and aquatic plants. Besides, it can also contribute to the stability of the water quality.
