PondMax Automatic Pressure Pond Filter with UV Clarifier 50000

PondMax Automatic Pressure Pond Filter with UV Clarifier 50000 – Self-Cleaning Pond Filter

The PondMax Automatic UV Pressure Filter 50000 is designed for large ponds, recommended for ponds up to 20,000 litres if fully shaded with no fish, or up to 10,000 litres if housing fish.

This external pressure filter combines mechanical, biological and UV filtration in one canister. Sponges and biomedia inside catch suspended debris, beneficial bacteria colonise this space to provide biological filtration, and an inbuilt UV globe keeps the water clear by preventing algae blooms.

Features & Benefits

• Cleaning indicator: an inbuilt buoy floats to the surface when the filter needs cleaning
• Automatic backwash: turn the blue switch to reverse the flow and push debris out through a secondary outlet, ready to direct to a drain or garden bed
• UV filtration: a 55 W UV globe kills harmful bacteria and suspended algae to prevent green water (replace the globe every 12 months, as its sterilising output drops even while the light still appears on)
• Timing switch: an inbuilt timer controls how long the UV light runs (we recommend running it 24/7 year-round in Australian conditions)

Installation and Pump Recommendation

This is an external canister filter that sits outside the pond in your garden or plant room, connecting via two lengths of 50mm hose. It should run alongside a properly sized pond pump; the maximum flow rate this filter can handle is 18,000 litres per hour, and we recommend running filters at their maximum flow for best performance.

For this filter, we recommend pairing it with the OASE Aquamax 17500 where there is little to no head height.

Head height is the height water needs to be pushed from the pond surface into the filter (and then into a waterfall, if applicable) before it returns to the pond. Pond pumps lose flow rate as head height increases, so where there is significant head height, you will need to size up the pump.

Recommended For

• Large ponds up to 20,000 L (no fish) or 10,000 L (with fish)
