FILTERLAV

Natural lava stone granules for biological and mechanical filtration for fresh and marine water aquarium. Lava stone is a material which comes out at the earth’s surface from underground, it is highly porous and free of organic polluting substances subject to decomposition. The exceptional highly porous structure of this material allows optimal conditions where the nitrifying bacteria, such as nitrosomonas and nitrobacter, can colonize and keep the aquarium water crystal clear.
