Natural pure Calcium Carbonate (CaCO3) in the form of natural oyster shells. Use substrate with excellent buffering qualities or as a sacrificial media. The rough surface of these shells makes them idea for rapid biofilm development.

Description & Application

Sea washed and dried natural oyster shells with a calcium carbonate content in excess of 96%.

These shells are the Japanese (Pacific) oyster which have been used extensively in that country to naturally achieve pH balance in Koi ponds. The shell's rigidity, biological stability and rough surface provides an ideal alternative to plastic substrate for active biofilm development.
