Pond Filters & Pumps UK — Crystal Clear Water All Year Round

A pond without adequate filtration quickly becomes green and unhealthy. Our range of UV clarifiers, pressure filters, and submersible pumps provides the biological and mechanical filtration needed for crystal-clear pond water — essential for koi health and wildlife habitat quality.

UV Clarifiers

Ultraviolet clarifiers kill single-celled algae (green water) by exposing pond water to UV light. Our UV pond clarifiers are combined with mechanical and biological filter media for a complete all-in-one filtration solution. Available in units suitable for ponds from 1,000L to 15,000L.

Complete Filter & UV Sets

Our complete pond filter UV sets include everything needed for clear pond water in a single unit — UV steriliser, mechanical filter foam, biological filter media, and pump (on selected models). Available for ponds up to 8,000L and 15,000L capacity.

Choosing the Right Filter Size

Filter capacity should be double the pond volume for fish ponds, or equal to pond volume for wildlife/ornamental ponds. For a 3,000L koi pond, choose a filter rated for 6,000L minimum. Always slightly over-specify — oversized filters are more forgiving of heavy fish loads and warm weather.
