Collected from the mineral-rich foothills of the famous Mount Aso volcano in Japan, Fluval Stratum is the ideal substrate to encourage the growth of aquatic plants in freshwater aquariums.

Plant roots easily penetrate the substrate and spread out, allowing plants to access a variety of important, readily available nutrients that help them thrive.

The addition of Fluval Plant Micro Nutrients ensures a complete supply of essential macro and micronutrients. The lightweight, non-compacting, porous structure of the substrate is also very beneficial for nitrifying bacteria, which quickly colonize the vast porous surface and provide optimal water quality for plants.

The inherent properties of Fluval Stratum support a neutral to slightly acidic pH, ideal for most plant species and types of tropical fish or shrimp typically kept in planted aquariums. Fluval Stratum also offers newborn shrimp the perfect refuge, allowing them to escape predators until they are large enough to emerge.

This highly attractive substrate does not discolor water and helps control organic staining that typically occurs when using natural driftwood.

Key features:

• Mineral-rich volcanic soil
• Stimulates strong plant growth
• Promotes a neutral to slightly acidic pH
• Suitable for plants or shrimp.
