Fluval Stratum - Infused with Beneficial Nitrifying Bacteria

  • Kick-starts the nitrogen cycle
  • Ideal for fine & delicate root systems
  • Helps support neutral to slightly acidic pH

 

Collected from the foothills of Mount Aso volcano in Japan, Stratum substrates include a powerful mix of nutrients and minerals to nurture healthy plant growth and water conditions.

Bio-Stratum features a 1-3 mm grain size, which is great for smaller aquariums, or as a top layer in larger systems. Infused with beneficial nitrifying bacteria, it's an ideal substrate to start a new planted aquarium with, especially if you plan to keep plants with more delicate root systems.

Note: If you are keeping a shrimp system, we suggest using the standard Fluval Stratum substrate instead as it has a slightly larger grain size, providing refuge for newborn shrimp. 



Maintains Ideal Water Parameters

Supporting a neutral to slightly acidic pH, Stratum substrates are ideal for live plants as well as tropical fish and shrimp commonly kept in planted aquariums. Stratum granules provide a natural way to soften water and reduce carbonate hardness, all without staining or discoloring aquarium water.
