Olibetta Gravel - Crystal Quartz 2-3mm, 5kg

This beautiful natural aquarium gravel from Olibetta is composed of harmonious shades of natural grains, making it ideal for your set-up. 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 size of 2.0-3.0 mm 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 have an active metabolism. The natural gravel should be rinsed briefly with cold water before use to remove transport-related abrasion.
