Hydrocarbonate 15 l bucket/21 kg fine - high purity calcium carbonate

hydrocarbonate is a pure natural product and is used in lime reactors, hardness filters, but also in biofilters and as a substrate in marine and Malawi/Tanganyika aquaria. It creates a natural lime/carbonic acid balance in all aquariums with an alkaline pH value. In calcium reactors, which are gassed with CO2, it dissolves completely and enters the solution as calcium bicarbonate. Available in 3 grit sizes: fine (1 - 2 mm) for hardening filters, medium (3 - 5 mm) for lime reactors and coarse (12 - 15 mm) as filter material.
