## Summary description

Tetra ActiveSubstrate 6 L (model 15932) is an aquarium substrate designed for planted aquariums. Supplied in a 6-litre package, it serves as a growth medium for aquatic plants and supports root development. Use it as a base layer in freshwater aquariums to improve plant anchoring and create a substrate suitable for planting, aquascaping and fish habitats.

## Long description

Tetra ActiveSubstrate 6 L is a specialist substrate formulated for freshwater planted aquariums. Supplied in a 6-litre bag, the substrate provides a stable base layer that supports root development, facilitates planting and contributes to an anchored, natural-looking aquascape. The product is intended to be used as the bottom layer beneath decorative gravel or on its own to create a nutrient-rich environment for aquatic plants and improved habitat structure for bottom-dwelling fish.
Advantages
Tetra ActiveSubstrate is designed to offer consistent granule size and composition that promotes root penetration and reduces compaction. It helps retain moisture and key nutrients at the root zone, supporting healthier plant growth without the need for frequent substrate replacement. The substrate is suitable for creating layered substrates and is compatible with common freshwater aquarium setups.
Suitable for
Planted freshwater aquariums
Establishing stable root beds for aquatic plants
Aquascaping and creating layered substrate systems
Environments for bottom-dwelling fish and invertebrates
Key specifications
Pack volume: 6 litres
Intended use: base substrate for planted freshwater tanks
Composition: plant-growth oriented substrate granules (designed for root support and nutrient retention)
Granule characteristics: uniform granule size to reduce compaction and allow root penetration
Compatibility: suitable for use under decorative gravel or as the primary planting layer
How to use
Rinse the substrate briefly if required by your water quality practice, then spread an even layer across the aquarium bottom, typically 2–5 cm for established plants or deeper where strong root development is desired. Place Tetra ActiveSubstrate as the base layer and cover with a thin layer of decorative gravel if desired. Plant aquatic species by gently inserting roots into the substrate and press lightly to ensure contact. When rearranging plants or cleaning, avoid excessive disturbance of the substrate layer to preserve root zones and nutrient distribution.
Usage recommendations
For new aquariums, set up filtration and perform initial water conditioning before introducing livestock. Combine the substrate with appropriate lighting and fertilisation tailored to the plant species used. Monitor plant health and add additional nutrient dosing if growth appears limited over several weeks.
