Lava rocks are of volcanic origin and are characterized by their porous texture, making them lightweight and versatile. This product has been polished into oval or round shapes to resemble river pebbles. They can be used in a variety of aquarium designs, including golf aquariums. Thanks to their lighter weight, it is possible to create large structures using them. Lava rocks do not increase the hardness of aquarium water.
