Olibetta Oli Pebbles Decorative Stones, Black 9 - 12 cm, 20 kg

These Olibetta natural pebbles with a size of 9 - 12 cm are great eye-catchers in any aquarium or aquascape. The natural oval-shaped pebbles are perfect for river aquariums and aquascapes with a calm, harmonious look.

The natural, rounded shapes look particularly beautiful in a flow tank, biotope aquarium or river aquarium. The uncoated pebbles do not harden the water. You can create varied and interesting designs in your aquarium or aquascape by using pebbles of different sizes. The pebbles look especially attractive in combination with Olibetta natural gravel or Olibetta coloured gravel.

The natural rounded pebbles are also ideal for making your own algae stones for your young and growing aquarium dwellers. Spread a paste of spirulina algae and water on the pebbles. Let them dry before placing in your aquarium. Wash the pebbles briefly in cold water before placing them in your aquarium to wash away any dust or debris caused by abrasion during transport. Also note that as these pebbles are natural products, the colours might vary slightly from the products pictured.
