Magnesium and Calcium release media for the Calcium reactor
Calciummagnesiumcarbonate (dolomite) is a natural product that aquarists use
mainly in Calcium reactors, but also in filter systems and as a substrate in
Malawi/Tanganyika aquariums. It increases the calcium and the magnesium levels
of the water. We recommend its addition at a rate of 25% to our hydrocarbonate.
