## Summary description

sera Gravel Ocher O is aquarium substrate in ochre color with grain size 0–2 mm, packed in a 3‑liter bag. Designed for freshwater aquariums, it provides a natural-looking bottom layer suitable for plants and small bottom-dwelling fish. Fine granules promote water flow through the substrate and support biological filtration and aesthetic layout.

## Long description

sera Gravel Ocher O 0–2 mm, 3 l is a fine-grained aquarium substrate in a natural ochre tone, supplied in a 3-litre bag for freshwater aquariums. The 0–2 mm grain size creates a compact, even bottom layer that supports plant placement and provides a gentle surface for small bottom-dwelling fish. The fine granules allow water to circulate through the substrate, contributing to biological filtration while producing a natural-looking aquarium layout.
Advantages
This aquarium gravel offers a consistent grain size of 0–2 mm, which helps to create an even and stable substrate layer. The ochre color gives a natural and neutral background that highlights plant growth and fish coloration without overwhelming the tank design. Fine granules improve water flow within the substrate, which supports beneficial bacteria and complements biological filtration processes. The 3-litre packaging is convenient for small to medium aquaria or for topping up an existing substrate.
Suitable for
Freshwater community tanks with plants
Aquaria housing small bottom-dwelling species such as Corydoras or small loaches
Layout designs requiring a natural, ochre-colored substrate
Planted tanks where a fine-grained top layer is preferred
Key specifications
Grain size: 0–2 mm
Color: ochre
Volume: 3 litres
Intended use: freshwater aquariums
How to use
Rinse the gravel briefly with dechlorinated water to remove dust before adding it to the aquarium. Spread the substrate evenly across the tank bottom to a depth appropriate for your plants and livestock, typically 2–4 cm for general setups or deeper where root-feeding plants are present. Place hardscape elements and plants after the substrate is arranged and fill the tank slowly to avoid disturbing the layer. Monitor water clarity during initial days and perform gentle cleaning if needed.
Usage recommendations
Use this fine 0–2 mm gravel as a top layer in planted aquaria or as a complete substrate in tanks with small bottom-dwellers. Combine with nutrient-rich substrate layers below if heavy root-feeding plants are used. For best results, avoid vigorous substrate stirring and perform regular gravel vacuuming in areas with accumulated detritus.
