Olibetta Gravel - Samurai 7-9mm

The carefully compiled Ollibetta aquarium gravel harmoniously matches in colour and is absolutely inert in water, it does not harden and does not give off any pollutants water.

The very coarse grain size is perfect for really large aquariums, but it can also be used in combination with a finer monochrome aquarium gravel or with a finer gravel mix as an eye-catcher and structural bringer. The edges of the large gravel grains are rounded, which greatly reduces the risk of injury to your aquarium inhabitants.

The coarse-grained Olibetta natural gravel mixture for aquariums is not only very decorative, but it also has a very positive effect on the biological climate in the aquarium and it keeps the pollutants low: all the gravel acts as an enormously large biological filter. The natural gravel should be rinsed briefly with cold water before use to remove transport-related abrasion.

The larger pebbles of our natural gravel mixes are perfect for bringing structure and variety into your aquarium. Indispensable for river aquariums!
