Cinnamon stick 8cm - Ceylon cinnamon 10 pcs.

Cinnamon bark contains astringent (astringent) tannins, essential oils and humic substances, which make the water suitable for fish and are effective against bacteria and fungi . Furthermore, the mucous membranes are protected and maintained, cinnamon bark can also prevent diseases .

This 8 cm long cinnamon stick is made of Ceylon cinnamon and thus contains very little harmful coumarin, unlike the often available in craft stores sticks of Cassia cinnamon.

In water, the cinnamon stick swells slightly and rolls up a bit, so that shrimp and small dwarf crayfish find a great hiding place here. The bark is very readily rasped off and provides minerals and important dietary fiber in addition to the valuable components listed above. As long as the active substances of the cinnamon stick are released, it has a reddish coloration. This will fade after a few weeks. Then you should add a new cinnamon stick. The "worn out" stick can remain in the aquarium as a cave or be removed.

The cinnamon stick is sufficient for 100 l aquarium water. For a smaller aquarium, shorten it accordingly with loppers or a sharp knife. Just put the cinnamon stick into the aquarium, it will sink after a short time.
