SV Natural Black Lava Rock for Aquarium

Black Lava is of volcanic origin, featuring a porous texture, making it very lightweight and versatile. Due to its comparably low weight, it is possible to create large structures with it. Plants like ferns or moss can be attached and their roots will find a good foothold due to the porous structure of the stone. As an advantage Black Lava does not increase the hardness of the tank water.
