Hows the coral bone stone formed?

After the coral dies, its body is gradually replaced by calcium carbonate combined with free CO2 and Ca cations in seawater. This process is called calcification, also known as petrochemical process. The result of this process is that the organic animal coral becomes inorganic.



Coral bone stone is formed naturally and it has lots of holes apparently looks from the appearance. It functions well to filter out impurities in aquarium water and provides a great home for nitrobacteria.


Suitable for freshwater, saltwater aquarium and pond.

It’s a good partner with Aquarium Pure to help you keep aquarium healthy and clear.
