■Product Description

■Notes
Please rinse the shells with water before use.
Handle with care as sharp edges may cause cuts. Rapid changes from acidic to alkaline conditions can harm aquatic life. Use in small amounts or adjust the water to near neutral by performing water changes before adding the shells. Use at your own risk.
