This Pressurised Pond Filter with built-in UV is designed to be continuously pressurised by the supplied Pond Pump, maintaining excellent water quality for healthy fishkeeping. Water is fed directly from your pond pump through to the filter container and subsequently the outlet, continuously under pressure. The water outlet can be located higher than the actual filter body, making it easier to disguise around the pond - particularly useful if incorporating a waterfall! Supplied with a fantastic new rotating cleaning handle on the head, maintaining the Pressurised Filter is now even easier! The unit will inform you when it is in need of a detailed clean using a small float, which pops-out of the head of the unit when required. By simply turning the handle you can rinse clean the interior sponge, eliminating the need to dis-assemble! Once rinsed, a separate outlet can be opened to discharge any dirty water until it runs clean and basic maintenance is complete. Each unit is supplied with a built-in UV Light, which effectively prevents growth of algae and eliminates harmful micro-organisms and parasites which may cause fish diseases.FiltrationWater passes through the PFC-12000 in the following order1) Pond water flows into the PFC-12000 via your pond pump2) Initial filtration begins by removing large particles through a mixture of coarse and fine filter foams (mechanical filtration)3) Then the water passes across bio balls that harbour good bacteria across large surface area (biological filtration)4) Lastly the exiting water is exposed to a 11w UV steriliser capable of reducing harmful bacteria and algae5) Clean, clear and healthy water exits your PFC-12000 and returns to your pond.
