Olibetta Gravel - Black Devil 3-4mm

This Olibetta aquarium gravel was sourced from visually attractive, perfectly matching and finely tuned natural gravels. This larger grain aquarium gravel causes a sensation as it can be used either alone in a correspondingly large aquarium or together with finer grains as an accent.

Especially in an aquarium or aquascape with a finer ground, a zone with coarser, more colourful natural gravel can be incredibly varied and relaxing. The Olibetta natural gravel mixture is a completely water neutral gravel and the edges of the grains are rounded - we guarantee that. The Olibetta natural gravel mix for aquariums is not only incredibly decorative, but it also has a favourable effect on the water quality in your aquarium because the gravel works like a gigantic biological filter, so that pollutants and water pollution can be rapidly reduced.

The natural gravel should be thoroughly rinsed with cold water before use to remove any abrasive debris and dust.
