Aquarium gravel sera Gravel Ocher O 0–2 mm 6 L — natural ochre substrate

sera Gravel Ocher O 0–2 mm 6 L is a natural ochre aquarium gravel designed for freshwater tanks. With a fine grain size of 0–2 mm and a 6-liter volume, the substrate creates a uniform, natural-looking floor layer that enhances contrast in planted and ornamental fish aquariums. The small particle size supports the planting of small-rooted aquatic plants and helps to stabilize lightweight décor while maintaining water circulation through the substrate.

Advantages

The ochre coloration provides a warm, natural background that highlights fish colors and plant foliage without altering water chemistry. The fine 0–2 mm grain enables secure anchoring for small-rooted plant species and allows for easy shaping during aquascaping. The substrate is pre-washed and ready for use, reducing initial cloudiness when setting up the aquarium.

Suitable for

• Planted freshwater aquariums with small-rooted plants
• Ornamental community tanks to enhance visual contrast
• Aquascapes and nano tanks where fine grain is preferred
• Terraces or shallow areas in aquarium layouts

Key specifications

• Grain size: 0–2 mm
• Color: natural ochre
• Volume per package: 6 liters
• Intended use: decorative substrate for freshwater aquariums
• Physical form: fine-grained gravel

How to use

Rinse the gravel briefly under running water until the outflow runs clear to remove any remaining dust. Spread an even layer of substrate on the bottom of the aquarium; typical depth for planted setups and small-rooted species is 2–4 cm, adjusted according to plant requirements. Add water slowly to avoid disturbing the gravel and arrange plants or décor as desired. Monitor initial water clarity and perform partial water changes if necessary during the first 24–48 hours.

Usage recommendations

For optimal plant growth, combine this fine-grained gravel with root tabs or a nutrient layer beneath the substrate when keeping nutrient-demanding species. Avoid aggressive digging fish directly on thin layers; increase substrate depth in areas where burrowing species are present.
