Aquascape UltraKlean 3500 Biological Pressure Pond Filter with 28W UV Clarifier, Black, 5,200 GPH

Aquascape's UltraKlean 3500 is a sponge-free biological pressure filter with an integrated 28W UV clarifier designed to deliver clear, healthy pond water for systems up to 3,500 gallons.

Engineered for both new installations and retrofits, the UltraKlean 3500 combines mechanical and biological filtration in a compact pressure-housed unit so you can place it out of sight while maintaining easy access for servicing. Its sponge-free layout reduces clogging and routine maintenance, while the included high-output T5 28 watt UV clarifier controls suspended algae and helps keep water clear. Rated for flows up to 5,200 gallons per hour, this unit supports medium to large backyard ponds and water features with reliable performance and a 3-year limited warranty.

How does the UltraKlean 3500 keep my pond clear?

The system couples mechanical straining and biological media to remove solids and foster beneficial bacteria that break down waste. The built-in UV clarifier neutralizes free-floating algae and certain microorganisms, improving water clarity without harsh chemicals.

• 28 watt T5 UV clarifier reduces suspended algae and cloudiness
• Included Aquascape UltraKlean bio media increases bacteria surface area
• Sponge-free mechanical path resists clogging and maintains flow
• Supports up to 3,500 gallon ponds for consistent clarity

What maintenance does this pressure filter require?

Maintenance is straightforward because the design avoids traditional sponges that trap debris and need frequent cleaning. Periodic rinsing of the mechanical chamber and exchanging or rinsing biological media as recommended will keep performance steady, and the UV lamp should be checked annually for output.

• Rinse mechanical chamber when flow slows or visible debris accumulates
• Inspect and rinse bio media during seasonal maintenance
• Replace UV bulb yearly for optimal clarifier performance
• Easy access lid and internal layout speed up service tasks

How do I integrate this filter into an existing pond or new build?

The UltraKlean 3500 is a pressure filter, so it can sit above ground level and connects to standard PVC or flexible plumbing for return and intake lines. Its compact, weather-resistant housing allows installation close to the pond or buried with easy access, and it works with most pond pumps up to the rated flow.

• Plumb in-line with your pump using appropriate fittings and valves
• Compatible with pumps delivering up to 5,200 GPH peak flow
• Weatherproof body for above-ground or partially buried placement
• Preloaded with Aquascape bio media for quick startup

What performance and warranty can I expect?

The filter is built for steady performance in backyard applications and supports ponds up to 3,500 gallons (13,000 liters). Aquascape backs the product with a 3-year limited warranty for part or manufacturing coverage, giving added confidence to homeowners and installers.

• Rated for ponds to 3,500 gallons / 13,000 liters
• Maximum flow handling up to 5,200 GPH
• Includes high-output T5 28 watt UV lamp and bio media
• 3-year limited warranty from Aquascape

Who is this for: The UltraKlean 3500 is aimed at homeowners, landscapers, and pond installers who need a low-maintenance, high-capacity filtration solution for medium to large backyard ponds and decorative water features. It suits projects where out-of-sight installation is preferred, where robust biological filtration is required, and where an integrated UV clarifier to reduce green-water issues is desirable. If you want a compact pressure filter that minimizes routine cleaning while supporting healthy pond ecosystems, this model is a practical choice.
