Aquarium Decorative Gravel ZOOLOGIA Aqua Natura Orinoco River 2–8 mm 0.8 kg

ZOOLOGIA Aqua Natura Orinoco River decorative aquarium gravel, grain size 2–8 mm, 0.8 kg pack, is designed to recreate a natural riverbed look in freshwater and planted aquaria. The neutral-coloured pebbles form a stable substrate layer or a decorative top dressing that supports plant roots, anchors ornaments and promotes a realistic aquascape. Suitable for use as a visible layer in planted tanks, a base for ornaments, or as an accent in terrariums and paludariums.

Advantages

The gravel provides a natural texture and colour palette that mimics riverbed environments while remaining chemically neutral for most freshwater setups. Its 2–8 mm grain size offers a balance between fine substrate and visible pebbles, allowing good water flow around roots and preventing excessive compaction. The product is lightweight and easy to distribute, making it simple to reshape layouts or add targeted decorative areas without heavy equipment.

Suitable for

• Freshwater aquariums
• Planted tanks as a top layer or substrate stabilizer
• Aquascaping accents and riverbed-style layouts
• Terrariums and paludariums for natural ground cover

How to use

Rinse gravel thoroughly with clean water before adding it to the aquarium to remove dust and fines. Spread an even layer across the tank floor—thickness depends on use: a thin decorative top layer of 1–2 cm for aesthetics, or 3–5 cm when supporting plant roots and decorations. Arrange larger features and plants after laying the gravel, and perform a partial water fill slowly to avoid disturbing the substrate. Monitor water clarity for the first few days and perform regular filtration and partial water changes as needed.

Usage recommendations

For planted tanks, combine this gravel with a nutrient-rich substrate beneath if long-term root feeding is required. Avoid using in systems with sensitive pH requirements unless compatibility is confirmed. Periodically siphon debris from the surface during maintenance to keep the gravel looking natural and to prevent detritus buildup.
