A good biofilter needs a lot of surface area with open spaces between for good aerated water flow. A high surface area is useless if the passageways are so small that water flow cannot penetrate.This light-weight versatile product is made of curly, fibre thermo-polypropylene compounds, and is non-toxic to the environment.
