    Extra solids filtration for the DIY'er. 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.  These plastic woven mats are formulated to allow water to pass through but small enough passages to trap large solid waste.
