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!
