, 15kg

The beautiful, dark colours of the natural pebbles of this coarse Ollibetta aquarium gravel natural gravel mixture of 13-15 mm size are harmonious and rather subtle. These relatively large stones with their rounded edges are great for very near-natural river aquariums or other natural aquariums. Round shapes also do well in aquascapes. Very nice to make a biotope for stream-loving animals. Also in the standard community aquarium, these little pebbles are great to look at, and you can be very imaginative and bring out the different shapes and colours. For very large pools, the coarse aquarium natural gravel mixtures from Olibetta are also super-suitable as a sole substrate or can also be combined with matching aquarium gravel or with a contrasting colour.

With this particularly coarse Olibetta natural gravel mix for aquariums you get a very decorative functional gravel, which has a large surface and thus works as a biological filter. The natural gravel should be rinsed briefly with cold water before use to remove transport-related abrasion.
