Aquarium substrate Tetra ActiveSubstrate 3 l — planted tank soil, nutrient-rich 3 L

Tetra ActiveSubstrate 3 l is a ready-to-use aquarium substrate formulated for planted freshwater tanks. This nutrient-rich soil layer supports aquatic plant root development and contributes to stable, healthy growth. Designed to be placed as a base layer beneath decorative gravel or sand, it supplies minerals and trace elements that foster strong root systems and sustained plant vitality.

The granule size and composition encourage root penetration while helping to retain nutrients where plant roots access them most. It is compatible with standard freshwater aquarium setups and can be covered with an aesthetic top layer to suit different aquascaping styles.

• Planted freshwater aquariums with rooted aquatic plants
• Establishing new aquarium substrates for long-term plant growth
• Layered substrate systems where nutrient base and decorative top layer are used
• Hobbyist and community tanks requiring improved plant rooting and mineral supply

How to use

Rinse is not required unless specified on the packaging; place Tetra ActiveSubstrate as the bottom layer of the aquarium substrate, typically forming a layer several centimetres thick depending on the plant species. Cover with a thin layer of decorative gravel or sand if desired to prevent clouding and to create the chosen aesthetic. Plant directly into the substrate by inserting roots or root balls to ensure contact with the nutrient-rich layer. When setting up a new tank, add water gently to avoid disturbing the substrate layers.

Usage recommendations

For optimal plant development, combine ActiveSubstrate with appropriate lighting, CO2 supplementation when required by high-demand species, and regular fertilization tailored to your plant selection. Monitor water parameters during initial weeks after setup to ensure stable conditions for both plants and fish.
