PondMax Pressure Filter/UV Clarifier PF9000UV

The Pressure Filter/UV Clarifier PF9000UV is a compact, all-in-one pond filtration system designed for medium to large garden ponds, typically up to 9,000 liters (around 2,400 gallons) depending on fish stock and sunlight exposure. It combines mechanical and biological filtration with integrated ultraviolet (UV) clarification to help maintain clear, healthy water.

This system features a pressurized canister filter, allowing water to be pumped through the unit and returned at an elevated level — ideal for use with waterfalls or raised outlets. The built-in UV clarifier helps control green water algae by exposing it to ultraviolet light, which clumps the algae together for easier removal through the mechanical filtration process.

The filter typically includes multiple layers of filter media, such as foam sponges for mechanical filtration and bio-media for beneficial bacteria colonization. A backwash cleaning system is often incorporated, allowing for easier maintenance without needing to open the canister.

The PF9000UV is compatible with a variety of pond pumps and is housed in a durable, weather-resistant casing suitable for year-round outdoor use.
