Pressurised Pond Filter featuring built-in UVC and 'Powerclenz' Automatic Cleaning SystemHALF RRP - Fantastic Value
By simply twisting a knob on this filter it automatically cleans itself! In the 'run' position the water undergoes a 4-stage purification process. Simply turn the knob to "Clean" and the foams are squeezed by up to 1,000lb of water pressure forcing out pond sludge. The back-flushed dirty water is then pushed out through the second waste outlet (typically down the drain or flowerbeds). This unit boasts a built-in 9w UVC and guarantees clear water for ponds up to 10,000 litres. (Figures based on pond in full shade with waterplants - 5,000 litres for ponds in full sun).
