## Summary description

Tetra CompleteSubstrate 5 kg is an aquarium substrate designed for freshwater tanks. Supplied as a 5 kg bag of natural-looking gravel, it provides a base layer for plants and decor, supports biological filtration by offering surface area for beneficial bacteria, and stabilizes décor and root systems. Suitable for hobby aquariums and plant setups.

## Long description

Tetra CompleteSubstrate 5 kg is a natural gravel substrate formulated for freshwater aquariums. Supplied in a 5 kg bag, this substrate creates a stable base for decorations and plant root systems while providing a textured surface that supports colonization by beneficial bacteria. Its natural appearance integrates with a variety of aquarium styles and helps maintain a balanced environment for common freshwater fish and plants.
Advantages
The substrate offers a consistent particle size and natural coloration that stabilizes décor and plant roots without releasing pigments or additives into the water. Its granular structure increases surface area for biological filtration and supports the establishment of nitrifying bacteria. Being ready to use out of the bag, it reduces preparation time for tank setup and is compatible with common freshwater aquarium maintenance routines.
Suitable for
Community freshwater aquariums with small to medium-sized fish
Planted tanks where a natural base layer is required for root development
Biotope-style setups that benefit from natural-colored gravel
Temporary or permanent substrates in starter and hobbyist tanks
Key specifications
Weight: 5 kg bag
Material: natural gravel
Intended use: freshwater aquariums
Particle characteristics: granular texture suitable for plant roots and bacterial colonization
Appearance: natural stone coloration for neutral aquarium aesthetics
How to use
Rinse the substrate briefly with dechlorinated water to remove any dust before adding it to the aquarium. Spread an even layer across the tank floor; recommended depth depends on planting needs but commonly ranges from 2–5 cm for simple setups and can be deeper for heavily planted tanks. Arrange décor and plants on top of the substrate and perform a partial water fill to avoid disturbing the layer. Start biological cycling using standard procedures and introduce livestock only after stable water parameters and established beneficial bacteria are achieved.
Usage recommendations
For planted aquariums, combine CompleteSubstrate with root tabs or a nutrient-rich layer below if intensive plant nutrition is required. Avoid aggressive substrate stirring during maintenance; perform gentle vacuuming of top debris and periodic partial water changes to preserve the substrate structure and support aquarium stability.
