AquaForte CBF-4000 Pond Pressure Filter with 9W UVC
The AquaForte CBF-4000 is a compact pressurised pond filter with foam filtration, biological support and an integrated 9W PL UV-C. It is aimed at smaller ornamental or lightly stocked ponds where the filter needs to sit discreetly and the return may continue to a small waterfall.
A selector valve provides a backwash route for routine cleaning, although the manufacturer is clear that thorough foam cleaning still requires the filter to be opened. Treat the backwash function as convenient maintenance, not a self-cleaning claim.

Sizing and maintenance
The maximum pond figure for this filter is stated without koi. Fish load, sunlight and feeding reduce the sensible capacity, so choose conservatively. Match the pump to the desired delivered flow after hose, lift and filter resistance and use the largest hose bore that the system allows.
Isolate the pump before changing valve position. Flush dirty water away from the pond, open and clean the foams when required, and inspect the quartz sleeve and UV lamp as part of the same service routine.
Our practical view: This is a sensible small pressure filter when expectations match the job. It is not a shortcut for a heavily stocked koi pond: modest fish load, regular flushing and an honest pump-flow calculation are what make it perform well.
Frequently asked questions
Is the pond-size figure for koi?
No. The manufacturer states that the maximum pond size is without koi.
Does backwashing clean it completely?
No. The foams still need periodic manual cleaning.
Can it feed a waterfall?
Yes, if the pump has enough delivered head after the filter and pipework.
What hose sizes fit?
The supplied hosetails cover 20, 25, 32 and 40mm.
Does UV-C remove sludge?
No. It helps control suspended green-water algae; the foam captures particles and still needs cleaning.
