Magic Volcano Rock/Black - Small / 12-18CM / box

The black volcanic stone is of volcanic origin and is characterized by a porous texture, making it lightweight and versatile in use. Thanks to its low weight, large structures can be created using it. Plants such as ferns or moss can be attached, and their roots will find a good home thanks to the stone's porous structure. One of the advantages is that the black volcanic stone does not increase the hardness of the aquarium water.

Weight: 10.5 - 11.5 kg, approximately. 17 pieces.
