Aquarium gravel AQUA DELLA Gravel Vulcano 2–5 mm, 10 kg

AQUA DELLA Gravel Vulcano 2–5 mm is a 10 kg bag of medium-grain aquarium substrate designed for use in freshwater and marine aquariums. The natural-looking granules create a stable base layer for plants and decorations while allowing water flow through the substrate. The 2–5 mm grain size balances stability with porosity, making it suitable for planted tanks, ornamental fish displays and invertebrate setups that require a consistent, easy-to-maintain bed.

Advantages

The gravel consists of uniformly sized 2–5 mm granules that promote even water circulation and support colonization by beneficial bacteria. Its medium grain size prevents excessive compaction while providing enough weight to anchor roots and décor. Packaged as a 10 kg bag, it covers a significant area at common substrate depths and is compatible with both freshwater and marine systems. The inert composition does not alter water chemistry, allowing predictable maintenance and stable aquarium conditions.

Suitable for

• Planted freshwater aquariums with root-feeding plants
• Community fish tanks requiring stable substrate
• Shrimp and invertebrate setups that prefer medium-grain gravel
• Marine and reef aquariums where inert ballast is required
• Aquascaping projects needing natural texture and appearance

Key specifications

• Granule size: 2–5 mm
• Package weight: 10 kg
• Color and texture: natural volcanic-like appearance suitable for neutral backgrounds
• Compatibility: suitable for freshwater and marine aquariums
• Physical properties: medium grain that balances porosity and stability

How to use

Rinse the gravel thoroughly with clean water before adding it to the aquarium to remove dust and fines. Spread an even layer of substrate on the tank bottom; typical depths range from 2 to 5 cm for decorative aquaria and up to 6–8 cm when promoting extensive plant root systems. Place plants, rocks and décor on top of the prepared layer and add water gently to avoid disturbing the substrate. Monitor initial cloudiness and perform gentle filtration and partial water changes as needed until water clears.

Usage recommendations

For planted tanks, combine this medium-grain gravel with root tabs or a nutrient-rich layer beneath if intensive plant growth is desired. Avoid aggressive siphoning near the substrate to maintain bacterial colonies and root stability. When used in marine tanks, ensure mechanical filtration removes suspended particles after initial setup.
