Lumen Pumice

Lumen Pumice is a natural volcanic glass that is formed when hot magma comes in contact with water. From this reason, an extremely foamy stone structure is created. Such a structure of stone provides an area of several hundred square meters for the colonization of positive bacteria useful for the removal of ammonia NH3, nitrite NO2 and nitrate NO3.

Before use, rinse well under running water to remove all dust!
