Blagdon Midipond 20000 Pond Filter
The Midipond 20000 is a higher-capacity box filter designed for ponds requiring increased flow and additional prefiltration. It combines ultraviolet, mechanical and biological filtration with added features to improve performance.
Water passes through the UV chamber before entering the venturi aeration chamber, which increases water and oxygen contact. It then flows over the Hydroscreen stainless steel prefilter, helping to remove larger debris before reaching the foam layers.
After mechanical filtration, water passes through ceramic biological media, followed by a polymer wool pad and carbon impregnated foam. Multiple outlet connections allow for higher return flow and more flexible pond circulation.

- Hydroscreen stainless steel prefilter
- Three foam layers with ceramic biological media
- Hosetail inlet connections for 19mm, 25mm, 32mm and 38mm hose
- 3 x 38mm outlet connections
- Supplied with 5m of cable
