HQUA 55W Pond UV Clarifier PWS-55 — Stainless Steel IP67 Reactor for Up to 8,000 gal, 2,700 GPH

The HQUA PWS-55 is a weatherproof 55W stainless-steel UV clarifier designed to reduce green water and suspended algae in ponds and pools up to 8,000 gallons.

This stainless-steel ultraviolet reactor combines a powerful 55W UV-C lamp with a durable 314-grade body and IP67 weatherproofing to deliver long-lasting clarification for outdoor water features and pools. Built for heavy-duty use, the PWS-55 resists degradation that can affect plastic housings, includes an easy-clean wiper rod for maintaining sleeve clarity, and accepts common hose sizes through supplied adapters. It’s designed to operate at flow rates up to 2,700 GPH while delivering sufficient UV dosage for clarifying applications.

How does the PWS-55 clarify cloudy or green pond water?

The unit exposes passing water to UV-C light that damages the cellular structure of free-floating algae and other microscopic particles, causing them to clump and be removed by your filter or settling. It’s sized and powered to provide a clarifying UV dose for ponds up to 8,000 gallons when installed with appropriate flow control.

• 55W UV-C lamp rated for clarifying performance
• Up to 2,700 GPH maximum flow for rapid circulation
• Designed to deliver ~16 mJ/cm2 UV dosage for clarification
• Combines UV action with mechanical filtration removal

What makes the stainless-steel reactor better than plastic models?

This reactor is fabricated from 314-grade stainless steel to resist UV-induced embrittlement and long-term degradation that can affect plastic housings. A metal body adds durability for outdoor and wet environments and helps ensure the unit remains chemically stable around aquatic life.

• 314 stainless-steel body for corrosion and UV resistance
• Recyclable, food-grade metal instead of polymer casing
• IP67 weatherproof rating for outdoor installations
• 1-1/2" FNPT inlet/outlet with included hose adapters for 1" and 1-1/2" lines

How do I install and maintain the HQUA PWS-55?

Installation requires inline plumbing with compatible fittings and a pump sized to avoid exceeding the 2,700 GPH maximum. Routine maintenance is straightforward: replace the UV lamp per the manufacturer schedule and use the supplied wiper rod to remove deposits from the quartz sleeve without disassembling the reactor.

• Mount inline with 1"–1-1/2" plumbing using included adapters
• Keep flow within recommended range for best UV dosage
• Use the attached wiper rod to clean the quartz sleeve easily
• Replace lamp and check seals annually or as instructed

Will this UV clarifier harm fish or plants?

When used correctly as an inline clarifier, UV-C light is contained within the reactor and does not reach the pond or pool, so it does not directly harm fish or plants. The unit is intended to treat free-floating algae and microbes passing through the reactor; it does not replace biological filtration or proper water chemistry management.

• UV light is confined to the reactor chamber only
• Safe for ponds and pools when installed per instructions
• Complementary to filtration and water quality practices

Who is this for: The HQUA PWS-55 suits pond and small pool owners who need a robust, weatherproof clarifier built from recyclable stainless steel instead of plastic. It’s aimed at hobbyists and professionals managing outdoor water features that require durable hardware, easy maintenance with an included wiper rod, and a clarifying capacity up to roughly 8,000 gallons when paired with correct pumping and filtration.
