Create a thriving aquatic environment with Fluval Bio Stratum, a premium, mineral-rich volcanic soil specifically formulated for planted freshwater tanks. Harvested from the foothills of Mount Aso in Japan, this high-quality substrate provides the essential nutrients and trace elements necessary to foster vigorous plant growth and vibrant foliage coloration. The unique, porous structure of these granules prevents soil compaction, ensuring that delicate and fine root systems can easily spread and anchor for a healthy, long-lasting aquascape. Beyond its physical properties, this substrate is infused with bioactive beneficial bacteria. These dormant nitrifying bacteria activate upon contact with water, helping to rapidly reduce ammonia levels and kick-start the nitrogen cycle in new aquariums. By naturally supporting a neutral to slightly acidic pH, it creates an ideal water environment for both aquatic plants and sensitive shrimp species. Whether you are maintaining a new aquarium or revitalizing an established planted tank, this volcanic substrate acts as an effective biological filtration medium, promoting superior water quality and stable conditions for your aquatic life to flourish.
