Olibetta Gravel - Black Zambia 3-5mm

This beautiful natural gravel mix from Olibetta for the aquarium is composed of different coloured natural grains. The aquarium ground does not harden or affect the water values.

With this very appealing natural gravel, you will set up your aquarium optimally. Let your imagination run wild and use different grains of the same colour mixture or different colours.

The Olibetta natural gravel mixture for aquariums is not only decorative but it also works like a large biological filter and ensures an optimal biological balance in the aquarium.

Due to the round shape of the gravel grains, there is no risk of injury to your aquarium dwellers. The slightly coarser grain works very well together with a floor washer or a floor heating. It is ideal for small community aquariums and also for larger aquariums with large residents who are blessed with an active metabolism. The natural gravel should be rinsed briefly with cold water before use to remove transport-related abrasion.

With the great natural gravel mixtures of Olibetta, you can design your aquarium to your liking. The slightly coarser grain can be perfectly kept clean, and the rounded gravel grains are very pleasant for your residents.
