Fluval Pond Pressure-Flo Pressurised Pond Filter with UV Clarifier
The Fluval Pond Pressure-Flo range delivers advanced, low-maintenance filtration for garden ponds and koi ponds. Designed for reliable year-round operation, this pressurised pond filter combines mechanical, biological and UV-C clarification to help eliminate green water, control algae and maintain consistently clear pond conditions.
The Easy-Clean backwash system allows external foam cleaning without opening the canister. This keeps maintenance quick, clean and low-mess while restoring filtration performance efficiently. Mechanical foam filtration captures suspended debris, helping maintain clear water and reduce visible waste.
Integrated BioLava biological media supports beneficial bacteria that reduce toxins and promote healthy pond fish and aquatic life. Built-in UV-C clarification helps eliminate algae and green water, supporting crystal-clear pond water throughout the season.
The pressurised design offers flexible installation. The unit can be positioned above ground, partially buried or fully hidden beside the pond. It can also support raised waterfalls, making it suitable for decorative garden pond layouts and water features.
A visible cleaning indicator shows when maintenance is required. The robust housing and Click-Fit hose connectors ensure secure installation and straightforward servicing.
For optimum filtration performance and water circulation, pair with a compatible Fluval Pond Max-Flo pump matched to your pond size and flow requirements.
