Aquarium lava rocks are volcanic natural substrates for aquascaping aquariums.

Highly porous volcanic rock
The highly porous volcanic rock has various tasks in an aquascaping aquarium: First, it provides a stable base for further constructions of stone and/or wood (roots), which would slip further down through the soil. On the other hand, many beneficial bacteria settle in the porous structure, contributing to a positive water environment. Furthermore, the porous rock structure provides good penetration of nutrients and provides many minerals, allowing plants to root and grow very well.
