■Product Description
These are Japanese oyster shell chips. They dissolve and neutralize when the water's pH becomes acidic. The size is approximately 4-8mm. Please refer to the photos for details.

■Notes
Please rinse the shells once before use.
Handle with care as sharp edges may cause cuts. Rapid changes from acidic to alkaline pH can negatively affect aquatic life. Use in small amounts or adjust the pH closer to neutral through water changes before adding. Use at your own risk.
