Our range of Pressurised Pond Filters with built-in UV Clarifiers are designed to be continuously pressurised by your pond pump, maintaining excellent water quality for healthy fishkeeping. Water can be 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, reducing 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.
