## Summary description

Sera Gravel Anthracite is aquarium gravel with grain size 1–3 mm supplied in a 3 L package. The antracite-coloured substrate is suitable for freshwater aquariums, providing a natural-looking bottom and stable base for plants and decor. Use for planting, biotope setups, and general aquarium substrate replacement or topping.

## Long description

Sera Gravel Anthracite 1–3 mm in a 3 L pack is a natural-looking aquarium substrate designed for freshwater tanks. The antracite colour and small grain size create a uniform bottom layer that supports planting, anchors decorative elements, and contributes to a stable habitat for aquarium inhabitants. The product is intended as a general substrate replacement or as a top layer to refresh existing gravel.
Advantages
The antracite colour provides a neutral, low-contrast background that enhances fish and plant colours while maintaining a realistic appearance. The 1–3 mm grain size balances water flow through the substrate and root penetration for many aquatic plants. Supplied in a practical 3 L package, the gravel is easy to distribute and suitable for limited volumes or for mixing with other substrates to achieve desired depth and texture.
Suitable for
Freshwater community aquariums
Planting tanks with small to medium-rooted aquatic plants
Biotope setups that require a natural, dark substrate
Replacing or topping existing substrate to refresh aquarium appearance
Key specifications
Grain size: 1–3 mm
Package volume: 3 litres
Colour: anthracite (dark grey)
Intended environment: freshwater aquariums
How to use
Rinse the gravel briefly under running water until the rinse water is clear to remove dust and fine particles. Spread the substrate evenly across the aquarium bottom to the desired depth, typically 2–5 cm for general use or deeper where planting is required. When planting, create small holes in the gravel, position plant roots, and gently cover the base to ensure secure placement. Combine with nutrient-rich substrates beneath if plants require additional root fertilisation.
Usage recommendations
For planted aquariums, use a nutrient substrate layer under the gravel if you keep heavy root feeders. Regular gravel vacuuming during water changes will help remove accumulated detritus while preserving the planted root zone. Avoid sudden changes in substrate depth that could disturb established aquarium inhabitants.
