Sea bleached and dried oyster shells offered to naturally achieve pH balance in ponds and a rough surface for active biofilm development.


Pack Size: 15kg

Shell size: Generally between 5-7.5cm in length.
The number of shells can vary but as a working guide 1kg is likely to contain approximately 40 to 50 shell pieces.

Description and Application:
Sea washed and dried natural oyster shells with a calcium carbonate content CaCO3 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.

Source: Oysters are one of the most widely farmed shellfish in the world - our shells are recycled from established food sources.

Background: Oysters are bivalve molluscs which live by filtering plankton in marine and brackish waters. Many varieties of oyster are prized foods being rich in zinc and other minerals.

Oysters in History: The Kent coast has been noted for its Oyster beds since Roman Times. Not only did the Romans eat the meat but the shells were burnt to form a very effective cement.

As our additional image shows, in the 19th Century oysters were seen as an inexpensive food by the working classes.
