Olibetta Gravel - Black Zambia 20-30mm

The colours of the natural pebbles of the coarse Ollibetta aquarium natural gravel mix of 20-30 mm are harmoniously blended. The pebbles are rounded and smooth and not only provide a truly stylish sight in your aquarium, but they are also very comfortable for the residents because they can not hurt themselves here on edges. For a natural river biotope in the aquarium or as a contrast to bright aquarium substrates, they are perfect. In a very large aquarium, even using it as the sole substrate would be conceivable.

With these pebbles, you can indicate a strong water flow in a river layout or implement a biotope for animals who like to live in the current. Also for the small community aquariums, these pebbles fit very well. You can relax the layout and set beautiful accents. The natural gravel mixture is also great when combined with matching aquarium gravel or with a contrasting colour.

With the particularly coarse-grained Olibetta Natural Gravel Mix in 20-30 mm you can get very decorative gravel. The natural gravel should be rinsed briefly with cold water before use to remove transport-related abrasion.
