## Summary description

Tetra CompleteSubstrate 10 kg is an aquarium substrate designed as a natural gravel mix suitable for planted and community freshwater tanks. Supplied in a 10 kg bag, it provides a stable base for aquatic plants and decor, supports root anchoring and biological filtration, and creates a natural-looking bottom layer for hobbyists maintaining freshwater ecosystems.

## Long description

Tetra CompleteSubstrate 10 kg is a natural gravel mix formulated for freshwater planted and community aquariums. Packaged in a 10 kg bag, the substrate provides a stable base layer that supports plant root anchoring and contributes to a balanced aquarium environment. Its neutral appearance helps create a realistic natural bottom while allowing biological processes such as colonization by beneficial bacteria that assist in nutrient cycling and filtration.
Advantages
The gravel mix combines particle sizes and a neutral mineral composition to support both rooted aquatic plants and free-swimming fish without altering water chemistry. It offers good mechanical stability for decorations and plants, promotes substrate aeration, and encourages colonization by nitrifying bacteria. The natural colour tones enhance visual harmony in planted and community tanks while remaining easy to arrange during aquascaping.
Suitable for
 Freshwater planted aquariums with rooted plants
 Community tanks with small to medium-sized tropical fish
 Biotope-style aquaria where natural visual appearance is desired
 New aquarium setups requiring a stable base layer for decor and planting
Key specifications
 Packaging weight: 10 kg bag
 Composition: natural gravel mix with mixed particle sizes
 Colour: natural neutral tones suitable for natural-looking aquascapes
 Chemical influence: formulated to be chemically inert, not intended to significantly change pH or water hardness
 Function: supports plant rooting, substrate stability, and biological filtration
How to use
Rinse substrate briefly if required by local handling instructions, then spread evenly across the aquarium base to create a layer of the desired depth for plant roots and decor stability. For planted tanks, provide a deeper planting area where roots can establish; for community tanks a moderate depth is sufficient to support decorative elements and allow burrowing species to behave naturally. Add water slowly to avoid disturbing the substrate and arrange plants and hardscape once the base layer is stable.
Usage recommendations
For optimal plant growth, combine the substrate with species-appropriate fertilisation and lighting. When establishing a new planted aquarium, consider layering finer planting substrate or root tabs in planting zones to support nutrient-demanding plants while using the gravel mix for general coverage. Routine gentle vacuuming of the top substrate surface during maintenance will remove debris without excessively disturbing root systems.
