Product Details:
The PondMAX SF Series All-in-One Filter combines a submersible pump, dual-density mechanical filtration, zeolite biological media, built-in UV-C clarifier, and fountain nozzle options into a single compact unit. Place it at the pond bottom, plug it in, and it handles everything — mechanical, biological, and UV filtration plus water movement and fountain display. Available in two models for ponds up to 750 gallons (no fish/shaded) or 1,000 gallons. Backed by a 2-year warranty.
FEATURES
- All-in-one submersible pond filter with built-in pump, UV clarifier, filtration system, and fountain nozzle
- Compact pond pump filter combo with UV ideal for small to medium ponds
- Large surface-area filter foams help reduce clogging from leaves and debris
- Durable lid design supports efficient filtration and debris separation
- Zeolite media supports beneficial bacteria growth and helps absorb ammonia
What’s Included In the Box
- SF All-in-One filter unit with 20 ft power cord (powers both pump and UV-C lamp from one cable)
- Side foam pad (lower density) — coarse mechanical filtration
- Top foam pad (high density) — fine particle mechanical filtration
- Zeolite filter media — biological filtration and ammonia absorption
- Built-in UV-C clarifier (9W — SF750 / 13W — SF1000)
- Swivel adapter — keeps fountain nozzle level on uneven pond bottoms
- Telescopic riser with flow-control diverter
- Three fountain nozzles: bell, tulip, lily
- Barb adapter for 3/4″ or 1″ tubing (stream/waterfall option)
- Lid with four clip fasteners and carry handle
HOW IT WORKS
Filtration Stage
- Water is drawn in through the top suction grid by the integrated pump — anti-clog design minimises debris intake.
- Water passes through the lower-density side foam sponge, capturing large particles and coarse debris.\Water passes through the high-density top foam sponge, capturing finer particles for thorough mechanical filtration.
- Water flows through zeolite biological media, which supports beneficial bacteria colonisation and absorbs ammonia.
- Water passes through the UV-C clarifier chamber where the lamp destroys free-floating single-cell algae (green water). A blue indicator light confirms the UV lamp is active.
- Filtered, clarified water exits through the 3/4″ outlet, powering the fountain nozzle, or redirected via the flow-control diverter to a stream, spitter, or waterfall.
Placement in pond
The SF Series filter sits on the pond bottom, fully submerged. The integrated pump circulates water through all three filtration stages (mechanical, biological, UV) and delivers clean water back through the fountain nozzle or an external outlet. Use a shim or riser if the telescopic tube at maximum extension does not clear the water surface. Level the unit so the nozzle is vertical for a straight fountain pattern. This self-contained all-in-one pond filter with UV is ideal for small to medium ponds where external filtration is not practical — one cord, no external plumbing.
INSTALLATION (7 ASSEMBLY STEPS)
- Place the UV-C lamp into the filter cage
- Place the assembled pump into the filter cage
- Place the lid/pump cover on top of the pump
- Insert the assembled telescopic riser and nozzle through the opening in the lid/pump cover; screw clockwise to connect to the pump
- Place zeolite filter media inside the filter cage; place the top filter pad around the nozzle and on top of the pump and UV lamp
- Place the lid around the nozzle and on top of the top filter pad
- Close all four lid clips to secure
PLACEMENT IN POND
- Place the assembled filter at the pond bottom — use a shim or riser under the filter if the telescopic tube at maximum extension does not clear the water surface
- Level the filter so the telescopic tube and fountain nozzle are vertical — this ensures the fountain runs straight
- Connect the power cord only after installation is complete — one cord powers both the pump and UV lamp
- The water flowing from the nozzle confirms the pump is working; the bright blue indicator light confirms the UV lamp is active
- Always lift the filter by the handle in the lid — never by the power cord. Attach a lanyard to the handle for easy retrieval from deeper ponds
FILTER MAINTENANCE
- Loosen the four lid clips and remove the lid (telescopic tube and nozzle do not need to be removed for routine cleaning)
- Pull out the top and side foam pads for rinsing — rinse in pond water, not tap water, to preserve beneficial bacteria
- For pump maintenance: unscrew the telescopic tube, remove the lid/pump cover, lift out the pump; unscrew the intake adapter screw, slide off the intake adapter (A), rotate the volute (B) counterclockwise to remove, then gently pull the impeller (C) out of its housing and clean with a small brush or mild soap
- Reassemble pump in reverse order — intake adapter and volute must be correctly oriented so the safety screw aligns
- For UV maintenance or lamp replacement — see Section 03c replacement parts and the instruction manual UVC Lamp Replacement procedure
- Winterisation: before temperatures drop below 32°F / 0°C, unplug, empty, remove from pond, and store in a dry sheltered location with the filter lid left open
