Fluval Bio-Stratum: Natural Mineral-Rich Volcanic Soil Substrate for Planted Tanks (17.6 lbs)

Fluval Bio-Stratum for Planted Tanks

Designed for lush, plant-focused aquariums, Fluval Bio-Stratum is a natural mineral-rich volcanic soil that supports root health and vibrant coloration. When introduced to your substrate, it helps create a micro-ecosystem that can break down waste and jumpstart the nitrogen cycle, contributing to more stable water conditions in both new and established tanks.

The substrate features fine powder granules that form a porous, non-compacting layer. This structure acts as an additional biological filtration source, while the lightweight 1 mm particles encourage delicate roots to explore, anchor, and spread through the substrate for resilient growth. The result can be healthier roots and more robust plant development, with color often becoming more vivid as roots establish themselves.

Key benefits

• Promotes robust plant growth with vibrant coloration for a thriving planted tank.
• Activates beneficial water conditions by jumpstarting the nitrogen cycle after setup.
• Stabilizes water conditions by helping to reduce ammonia levels in both new and established tanks.
• Enhances root penetration with non-compacting 1 mm powder granules, supporting delicate root systems.
• Improves water quality through porous granules that host beneficial bacteria and nutrients.

Real-world use

In everyday setups, hobbyists may notice richer plant coloration, stronger root networks, and a sense of overall balance as the substrate works with filtration to support a healthier ecosystem. The soil’s mineral blend complements standard aquarium filters and aids in maintaining clearer, more stable water as roots grow and microbes establish themselves.

• Ideal as the primary substrate in new planted tanks, helping to establish a foundation for growth.
• Suitable as a supplementary layer in established tanks to enrich root zones and water quality.
