Fluval Bio-Stratum Volcanic Soil for Planted Tanks | 8.8 lb Mineral-Rich Substrate

Enhance Your Planted Tank with Fluval Bio-Stratum

Designed for aquariums that showcase lush aquatic plants, Fluval Bio-Stratum is a natural mineral rich volcanic soil substrate that brings an earthy, tactile foundation to the bottom of your tank. Its fine powder granules promote biological activity while remaining non-compacting, so roots can spread with ease and plants can establish themselves more confidently.

As water enters the substrate, dormant bioactives wake, beginning processes that support a balanced environment. The result can be clearer water and more vibrant plant colors as the substrate contributes minerals and fosters a porous bed that acts as an extra layer of biological filtration. This blend is crafted to work with the ecosystem you build, not to overwhelm it, offering a stable backdrop for both newcomers and seasoned hobbyists alike.
