Calcium carbonate gravel, white

Calcium carbonate crush, white, is an optimal material for lime reactors. The high degree of purity guarantees high performance. This material can also be used as a substrate for seawater aquariums and East African cichlids. It buffers formed acids and thus stabilizes the pH value of the aquarium water. In a filter after reverse osmosis systems, the water is stripped of the aggressive carbonic acid and enriched with minerals (mineral filters). 

• high purity
• high and fast dissolubility
• edged shape with 3 to 5 mm
