Medium-Density Rigid Filter Mat for Balanced Pond Filtration
The Aquascape Medium Density Rigid Filter Mat bridges the gap between coarse mechanical and biological filtration, suitable for mid-stage use in multi-chamber filters or as a single-medium filter mat where one stage must handle both functions. It captures mid-size particles while supporting beneficial bacterial colonisation on its porous foam surface.
Versatile Mid-Stage Media for General Pond Filtration
Where pond load is moderate and a three-stage setup is not practical, the medium-density mat handles both roles adequately. It captures more fine particulate than low-density foam while providing better bacterial surface area than high-density. In a two-mat setup, pair it with a high-density coarse mat upstream and a low-density bio mat downstream for a complete three-stage system in a standard two-chamber housing.

How to Use
Place mid-stream in the filter housing, after any coarse pre-filter media. Rinse every 3 to 5 weeks in pond water to clear accumulated solids. Avoid tap water to preserve beneficial bacteria. Replace annually or when the mat compresses permanently.
Ideal for moderate-load ponds where a single versatile filter mat handles both particle capture and bacterial support, or as the middle stage in a full three-media filter setup.
