🌱 Fluval Bio-Stratum Plant & Shrimp Substrate – 17.6 lb (8 kg)

Fluval Bio-Stratum is a premium active volcanic soil substrate engineered to promote strong root development, vigorous plant growth, and enhanced biological filtration in freshwater aquariums. Its porous structure actively supports the growth of beneficial nitrifying bacteria, helping aquariums establish and maintain a healthy nitrogen cycle.

Bio-Stratum gently buffers water toward a slightly acidic pH, making it especially well-suited for shrimp colonies, planted aquariums, and soft-water fish. The 17.6 lb (8 kg) bag is ideal for medium to large aquascapes, full substrate coverage, and advanced planted tank layouts.
