Fluval Pond Pressure-Flo Filter with UV – 4500L

Keep your garden pond looking its best with the Fluval Pond Pressure-Flo Filter with UV 4500L. Designed for ponds up to 4,500 litres, this pressurised filtration system combines mechanical filtration with an integrated ultraviolet clarifier to help maintain cleaner, clearer water for ornamental ponds and fish ponds.

The Pressure-Flo features a multi-stage filtration system that captures suspended debris while providing UV clarification to help control the free-floating algae responsible for green pond water. Its sealed, pressurised design allows filtered water to be returned to the pond or directed to a suitable waterfall or water feature.

One of the standout features is the convenient backwash cleaning system, which allows the filter foams to be cleaned without opening the canister. Built-in cleaning indicators help identify when maintenance is required, making routine filter care simpler and more convenient.

Ideal for pond owners looking for effective filtration with easy maintenance, the Fluval Pressure-Flo provides a practical solution for maintaining water clarity and supporting a healthy pond environment.

Regularly inspect the filter foams, UVC lamp, quartz sleeve and seals. Replace the UVC lamp according to the manufacturer's maintenance recommendations.

Install the filter in a suitable, well-ventilated location at least one metre from the pond edge, and follow all manufacturer safety instructions.
