Fluval Bio-Stratum is a porous substrate for planted aquariums and shrimp tanks, made from material harvested in the mineral-rich foothills of Mount Aso in Japan. The 1 mm granules do not compact, allowing fine roots to penetrate and spread, while absorbing nutrients, minerals, and trace elements.
The substrate is infused with dormant nitrifying bacteria, which activate on contact with water and help start the nitrogen cycle. It helps reduce ammonia quickly and stabilize water conditions in new aquariums. The porous granules encourage bacterial colonization and provide an additional source of biological filtration. It helps maintain a neutral to slightly acidic pH, softens the water by reducing carbonate hardness, does not discolor the water, and helps control discoloration. Special hardening and heat treatment help extend its lifespan and ensure it is free of parasites.
