How to use

Rinse the polished stones thoroughly under running water before introducing them to an aquarium or terrarium to remove loose dust and small particles. For aquatic use, perform an additional soak and rinse until the water runs clear. Place stones directly onto the tank or terrarium floor or mix with existing substrate to create desired contours and hiding spots. Arrange stones to avoid creating unstable stacks that could shift and injure inhabitants.

Usage recommendations

For aquariums with sensitive fish or invertebrates, monitor water parameters after adding the stones for the first time; perform regular checks for dust or fine particles that may require additional rinsing. Avoid using stones that show signs of crumbling or sharp edges. When used in planted aquaria, leave space for plant roots or combine with finer substrate to support rooting species.
