Simple setup and care tips

Preparing and using the gravel is straightforward. The material is colorfast and non-toxic, so it supports decorative and display projects without affecting water chemistry when used as directed. For best results, plan your layout with a slim, even layer and avoid stacking the stones too high near tank walls to keep fish comfortable.

• Rinse the decorative stones 3–4 times before adding them to a tank or planter
• Aim for a shallow, even layer to protect aquatic life and plant roots
• Use the guideline L W / 23 lbs for a 1" layer in an evenly shaped tank
• Example: a 10" x 10" tank needs about 4.35 lbs for a 1" layer

With its smooth edges, colorfast surface, and multi-use appeal, this gravel offers a vibrant yet balanced way to refresh living spaces or creative setups.
