This Japan Filter Mat is made from tough and long lasting material to support a strong bacteria culture capacity.
- The mat offers a large specific area for beneficial nitrifying bacteria to establish their colonies.
- The pond mat also offers excellent water permeability. Even when multiple mats are stacked on one another, it will not affect water circulation.
- Due to its high density fibers, the mat retains its shape and rigidity for a longer service life. You can cut it to whatever size you wish.
