Aquascape 95060 UltraKlean 3500 Pond Filtration Kit – Complete BioFilter w/ UV Clarifier & Pump for Ponds Up to 3,500 Gallons

The Aquascape UltraKlean 3500 kit (95060) is rated for ponds up to 3,500 gallons. For ponds with heavy fish loads or koi, a general pond sizing guideline recommends approximately half the rated capacity — around 1,750 gallons — to allow adequate filtration margin for higher waste loads and nutrient levels.

This recommendation reflects the extra biological oxygen demand, ammonia production, and solid waste output of koi compared to lighter ornamental fish loads. For optimal results with koi, ensure the AquaForce 5200 pump is running continuously and the UV lamp is replaced annually to maintain algae control.

The UltraKlean 3500 includes a 28-Watt T5 UV clarifier/sterilizer integrated directly into the filter body. As water passes through the UV chamber, the UV light destroys the DNA of single-celled floating algae — the organism responsible for “green water.” Damaged algae cells clump together and are then trapped by the BioBall media on the next filtration pass, progressively clearing the water.

Key UV features: the swirl sleeve design maximizes water’s exposure time to the UV lamp for more effective treatment. The electronic bulb-saver function protects the lamp from voltage spikes, extending bulb life. The UV lamp should be replaced annually — even if it still glows, UV output diminishes significantly after 12 months of use.

The 95060 kit includes the Aquascape AquaForce® 5200 Solids-Handling Pump (SKU 91013). Key specifications:

• Max flow rate: 5,284 GPH
• Motor: 360W asynchronous (energy-efficient; saves significantly vs traditional pumps)
• Max head height: 24 feet
• Power cord: 25 feet
• Discharge: 1.5″ MPT (optimum pipe: 1.25″–2″)
• Solids handling: passes solids up to ¼″
• Design: oil-free asynchronous; protective pre-filter cage; rotational ball output for adjustable discharge; wide flat base for in-pond placement
• Warranty: 3-year limited

The AquaForce 5200’s asynchronous motor delivers high-torque, 24/7 continuous-duty performance. The protective cage allows the pump to sit directly in the pond, and the pre-filter cage handles debris without clogging. The pump can also serve as a winter pond de-icer to keep a hole open in ice for overwintering fish gas exchange.

The UltraKlean 3500 features a backwash valve for cleaning without opening the canister. When the cleaning indicator light illuminates, follow these steps:

• Switch the dial valve from the “filter” to the “clean” setting.
• The backwash action agitates the BioBalls and reverses flow, flushing accumulated debris out through the discharge line.
• The entire process takes under 5 minutes without opening the canister or getting hands dirty.
• Switch the valve back to “filter” when complete.

Because the UltraKlean uses BioBalls rather than sponge media, cleaning frequency is reduced compared to sponge-based filters — BioBalls resist compaction and allow more even water flow between cleanings. Cleaning frequency varies by fish load, feeding rate, and seasonal conditions; the indicator light ensures you clean only when needed rather than on a fixed schedule.

Yes. The UltraKlean’s pressurized canister design allows it to be buried up to the lid in the ground, making it easy to hide within the landscape while still providing full access to the lid for backwashing and maintenance. This is one of the key advantages of pressure filters over gravity-return filters (which must remain above pond water level).

Because filtered water exits the UltraKlean under pressure, you can route the output pipe uphill to a waterfall or stream located above the filter’s elevation — something that is not possible with gravity-flow systems. Ensure the lid remains accessible above grade for cleaning.

For peak UV performance, replace the 28W T5 UV lamp once per season (approximately every 12 months of use). UV lamps lose output effectiveness significantly over time even when they still visibly glow — this is why Aquascape includes an electronic bulb-saver to extend life, but annual replacement is still required. UV lamp and quartz sleeve are not covered by the 3-year limited warranty as they are consumable items.

The quartz sleeve (the transparent tube surrounding the UV lamp) should be cleaned periodically and replaced if cracked, cloudy, or damaged. A fouled quartz sleeve reduces UV transmission and can render the UV stage ineffective even with a new lamp.

Aquascape offers three UltraKlean filtration kit sizes:

• 1500 Kit: UltraKlean 2000 filter (14W UV) + AquaForce 1000 pump (1,070 GPH, 55W) — ideal for smaller ponds up to 1,500 gallons
• 2500 Kit: UltraKlean 2000 filter (14W UV) + mid-range AquaForce pump — for ponds up to 2,500 gallons
• 3500 Kit (95060, this): UltraKlean 3500 filter (28W T5 UV) + AquaForce 5200 (5,284 GPH, 360W) — for ponds up to 3,500 gallons

The 1500 and 2500 kits share the same UltraKlean 2000 filter body with a 14W UV lamp. The 3500 kit uses the larger UltraKlean 3500 filter with double the UV wattage (28W) and the most powerful AquaForce pump in the series. If you have koi or a heavily stocked pond near the upper capacity limit of a smaller kit, upgrading to the 3500 kit provides meaningful headroom.

Yes. The AquaForce 5200’s asynchronous motor technology delivers high flow rates (5,284 GPH) at 360 watts — a significantly better flow-per-watt ratio compared to traditional magnetic-drive pump designs at equivalent flow rates. Aquascape estimates the asynchronous design saves hundreds of dollars annually in electricity costs versus traditional pumps at this performance level.

The pump is designed for 24/7 continuous-duty operation, making it suitable for year-round pond filtration including winter months. In winter, the AquaForce 5200 can be operated at reduced flow to maintain a hole in pond ice for fish gas exchange — essentially functioning as a de-icer.

Yes — the UltraKlean 3500 kit is designed for easy integration into both new and existing ponds. Because it is a pressure-side filter (the pump pushes water through rather than relying on gravity), it can be added to almost any pond configuration:

• Place the AquaForce 5200 pump in your existing pond (it sits directly in the pond via its pre-filter cage and wide base).
• Route the 25 ft of kink-free pipe from the pump to the UltraKlean 3500 filter inlet.
• Connect the filter outlet to your waterfall, stream return, or pond return jet.
• Set the 2-way flow control valve to optimal flow and use the dial to fine-tune.

The entire installation can typically be completed in a few hours. The 3-year limited warranty covers the filter and pump from the date of purchase.

The Aquascape 95060 kit carries a 3-Year Limited Manufacturer's Warranty covering both the UltraKlean 3500 filter and the AquaForce 5200 pump against defects in materials and workmanship from the date of purchase.

The following items are excluded from warranty coverage as they are consumable items with a normal service life:

• UV lamp — replace annually for peak UV performance
• Quartz sleeve — periodic cleaning and eventual replacement
• BioBalls (filter media) — replace as needed based on condition
