Olibetta Gravel - Black Zambia 8-10mm
The coarser grain size of the Ollibetta aquarium natural gravel mixture of 8-10 mm is carefully matched in colour and is perfectly suited to make the ground in a large aquarium or aquascape or in a smaller pool for structuring and contrast. The gravel can be used in the aquarium and aquascape with colour matching or with contrasting aquarium gravel.
The small pebbles are water neutral and do not affect water hardness. The edges of the large gravel grains are rounded, which greatly reduces the risk of injury to your aquarium inhabitants. The particularly coarse-grained Olibetta natural gravel mixture for aquariums is not only super decorative but it also has a practical added benefit: it keeps the organic load in the aquarium low: The gravel works as a biological filter. The natural gravel should be rinsed briefly with cold water before use to remove transport-related abrasion.
Our expert Oliver Knott recommends:
The larger pebbles of this natural gravel mix are particularly well suited to river aquariums and aquascapes in which different gravel sizes should be used.
