Natural coral crushed for marine and freshwater aquariums. Grain size 20–25 mm. Sold by the kilo.

Crushed coral can be used as substrate, decoration, or filter material. In saltwater aquariums, it is also suitable as a calcium reactor media. In freshwater aquariums, crushed coral can increase water hardness and KH value, making it particularly suitable for species that prefer harder water.

Rinse the crushed coral thoroughly before use. Use sparingly if the aquarium houses species that prefer soft and acidic water.
