Exo Terra Sub Stratum Bioactive Volcanic Substrate For Reptile Terrariums And Planted Vivariums 4 Kilograms

Transform your reptile terrarium into a self-sustaining ecosystem with the Exo Terra Sub Stratum Bioactive Volcanic Substrate. Sourced from the mineral-rich foothills of Japan's Mount Aso, this natural volcanic soil consists of andesitic and rhyolitic tephra packed with essential nutrients for lush plant growth. Designed specifically for bioactive terrariums and planted vivariums, its porous structure offers superb drainage and aeration to prevent waterlogging and encourage robust root development. This lightweight soil features active carbon and dormant beneficial nitrifying bacteria that activate upon contact with moisture. These beneficial organisms efficiently decompose organic waste, control ammonia levels, and neutralize unpleasant odors to maintain a clean environment for your reptiles and amphibians. Ideal for hobbyists seeking a natural foundation, this versatile substrate can be used as a sole layer, integrated into a drainage setup, or blended with other organic materials to enrich mineral content.
