Fluval Bio Stratum 17.6 lbs.
Fluval's 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 x001F filtration, Bio-Stratum's smaller powder format granules are porous and non-compacting, which further promotes bacterial colonization and enhanced water quality.
