Fluval Bio-Stratum Plant & Shrimp Substrate 8.8 lb (4 kg)
Fluval Bio-Stratum is an advanced active volcanic soil substrate designed to support vigorous plant growth, strong root development, and healthy biological filtration. Unlike standard substrates, Bio-Stratum actively encourages the growth of beneficial nitrifying bacteria, helping establish and maintain a stable aquarium ecosystem.
It gently buffers water toward a slightly acidic pH, making it an excellent choice for shrimp, live plants, and soft-water freshwater fish. The 8.8 lb bag is perfect for small to medium planted aquariums and shrimp colonies.
