Olibetta Gravel - Tanganyika Black 2-3mm

The colourful Olibetta gravel for the aquarium is guaranteed to be free from harmful substances. We work according to the DIN EN 71, part 3, so that our gravel corresponds to the German industry standard for toy safety.

Thanks to its coating with a lasting, elastic synthetic resin, the gravel leaches absolutely nothing into the water, it is resistant to chemicals and CO2-resistant. You can use the gravel either alone or as a coloured accent, you can mix the colours or use them parallel to each other and play with different grits ... your imagination knows no bounds here.

In addition to its decorative function, Olibetta gravel also has a positive effect on the biological balance, as it acts as a natural biological filter. Its rounded shape ensures that your aquarium dwellers can not hurt themselves. The different grain sizes are recommended for small community aquariums and especially for larger aquarium animals with an active metabolism.
