Fluval Bio-Stratum Aquarium Substrate

Providing the same powerful mix of nutrients and minerals as original Fluval Stratum for explosive plant growth, Fluvals All-New Bio-Stratum is infused with beneficial bioactive bacteria that will break down waste, kickstart the nitrogen cycle and rapidly reduce ammonia levels to help stabilize water conditions in new aquariums and keep the established aquariums healthy. Acting as an additional source of biological filtration, Fluval Bio Stratum powder format granules are porous and non-compacting, which further promote bacterial colonization and enhanced water quality.

Made from 100% natural, mineral-rich volcanic soil from Mount Aso in Japan and infused with beneficial nitrifying bacteria, Fluval Bio-Stratum is specifically formulated to provide immediate biological activity and maintain ideal conditions for a thriving planted aquarium. Characterized by its non-compacting 1 mm powder granules, Fluval Bio-Stratum allows plants with even the finest and most delicate roots to easily spread throughout the porous substrate while absorbing a powerful mix of nutrients, minerals and trace elements that promote explosive growth and overall health.
