Blue Coarse Filter Mat for fish pond filtration(500x500x40mm)

This Blue Coarse Filter Mat for fish ponds is made from superior material to support a strong bacteria culture capacity and mechanical filtration (pre-filtering out most coarse solid waste)

Measures: 500x500x40mm

• The mat offers a large specific area for beneficial nitrifying bacteria to establish their colonies. 
• This mat can also be used as a mechanical pre-filter to filter out most coarse solids coming from the fish pond. You can add a Finer Filter mat underneath the Blue Coarse Filter mat, to further filter out the finer fish waste particles.
• 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 quality fibres, the mat retains its shape and rigidity for a longer service life. You can cut it to whatever size you wish.

Ideal for Koi Pond Filter Systems, Fish Farms and Aquaculture filtration
