• 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.
