Fluval Pond Pressure-Flo Filter with UV – 21,000L

Keep your pond water cleaner and clearer with the Fluval Pond Pressure-Flo Filter with UV 21,000L. Designed for large garden ponds, this pressurised filtration system combines mechanical filtration with integrated ultraviolet clarification to help control green water and maintain a healthier aquatic environment.

The Pressure-Flo uses mechanical filter foams to capture suspended debris, while the integrated UVC clarifier helps control 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 compatible waterfall or water feature, offering flexibility for larger pond installations.

The convenient backwash cleaning system allows the filter foams to be cleaned without opening the canister, while a built-in cleaning indicator helps identify when maintenance is required. This makes routine filter care more straightforward for pond owners managing larger systems.

Ideal for large ornamental ponds, the Fluval Pressure-Flo offers a practical combination of mechanical filtration, UV clarification and convenient maintenance.

Installation and Maintenance

Connect a suitable pond pump to the filter inlet and use appropriately sized hoses to return filtered water to the pond. The outlet may also supply a compatible waterfall or water feature, provided the pump delivers sufficient flow at the required operating height.

Regularly inspect and clean the filter foams, UV lamp, quartz sleeve and seals. Use the backwash function according to the manufacturer's instructions and replace the UV lamp as recommended.

Please note: The pump is sold separately. The advertised pond capacity is a guide and depends on fish stocking levels, feeding, sunlight exposure and organic debris. Heavily stocked ponds may require additional filtration. Confirm the exact model specifications and installation requirements before use.
