About Blagdon Clean Pond Machine 10,000
The Blagdon Clean Pond Machine 10,000 (CPM 10000) is a pressurised pond filtration unit that combines a foam‑free 2‑in‑1 CHI media (mechanical + biological) with an integrated UVC clarifier. The manufacturer states the UVC lamp for this model is 11 W and that the maximum permitted flow through the UVC chamber is 5,000 litres per hour; the manual explicitly warns not to exceed that flow rate. The unit is supplied with three multi hose tails to fit 1 1/2", 1 1/4", 1", and 3/4" hose diameters and the product page lists a recommended hose size of 25 mm (1"). The filter is described by the manufacturer as suitable for a range of pond scenarios in the official sizing table: for example, up to 10,000 L for over‑75 cm deep ponds without fish (in shade), and smaller capacities for ponds with fish or koi (the manual gives several condition‑specific capacity figures). The product carries an IP57 rating and the manufacturer documents a 3‑year unit guarantee plus a lifetime CHI media guarantee. The manual includes a turn‑to‑wash backwash handle and notes a UVC micro‑switch that prevents lamp operation when the cover is removed; an indicator window allows lamp operation to be checked. Manufacturer documentation provides two differing dimensional and head figures (see limitations). The manual also recommends annual replacement of the UVC lamp and gives installation guidance (short hose runs, smooth‑bore outlet hose, avoid kinks). This description reflects only the first‑party manufacturer data supplied in the product page and instruction manual.
Best for
Ponds without fish up to 10,000 L (over 75 cm deep, in shade); smaller fish and koi ponds per the manufacturer sizing table (see description).
Things to consider
Manufacturer documentation contains conflicting first‑party values for two items: (1) Maximum head/pumping height — the product page lists 7 m, while the instruction manual states the filter outlet must be at no more than 4 m head height above the lid. This conflict is unresolved in the supplied materials, so no single head value is recorded. (2) Dimensions — the product page and the instruction manual list different assembled dimensions (product page: 37.5 x 39.8 x 36.5 cm HxWxD; manual: 40 x 42 x 42 cm W×D×H). Manufacturer first‑party sources do not provide a valid unit weight (product page shows a placeholder 0.0000 kg). Operating pressure (bar/kPa) and any electrical consumption beyond the listed 11 W UVC lamp are not stated in the supplied documentation.
Installation
Follow the manufacturer manual: unit may be installed above ground or buried to the bottom rim of the head unit leaving UVC access. Manual recommends shortest possible hose runs, smooth‑bore outlet hose and avoid kinks. Use recommended hose size (25 mm / 1") and supplied multi‑hose tails as required. The manual states the outlet should be no more than 4 m above the lid (see limitations for conflict with product page).
Maintenance
Manufacturer recommends annual replacement of the UVC lamp. Unit uses a turn‑to‑wash backwash mechanism for routine cleaning. CHI media is stated as a lifetime guarantee item and is not listed as separately available in manual.
Safety
UVC lamp is protected by a micro‑switch to prevent illumination when the cover is removed. Do not exceed the manufacturer‑stated maximum flow through the UVC chamber (5,000 L/hr). Observe IP57 ingress protection recommendations and electrical safety instructions in the official manual.
