Description

Activated Volcanic Lava has an incredibly porous structure to its cells, meaning that it offers a larger surface area for the development of nitrifying bacteria. This makes it an impressive filter medium, with several times the surface area of other media available. It is ideal for any pond or tank filtration system and is also cost effective when used in large set-ups.
