HALF OFF PONDS Shock Wave 55W UV In-Line Clarifier for Ponds up to 6,000 gal — Quartz Sleeve, 2,000–3,000 GPH

The HALF OFF PONDS Shock Wave 55W in-line clarifier is a 55-watt UV light system designed to reduce algae and suspended particles for clearer ponds and water features up to about 6,000 gallons.

Installed inline with existing mechanical and biological filtration, this compact clarifier uses a quartz-sleeved 55W bulb and engineered flow fittings to expose pond water to ultraviolet light, helping cloudiness settle and improving overall clarity. The unit is built with a durable 2.5" outer housing, a 22-foot cord and an integrated transformer for 120V power. It’s intended as an adjunct to proper filtration and circulation, not a replacement for maintenance or biological balance.

How does the Shock Wave 55W help clear cloudy water?

The UV bulb emits ultraviolet light that neutralizes free-floating single-cell algae and other microscopic organisms, allowing them to clump and be removed by your mechanical filter. Continuous exposure as water circulates past the quartz sleeve improves clarity over days to weeks, depending on pond load and flow rate.

• 55-watt UV bulb rated for approximately 9,000 hours of operation
• Quartz sleeve ensures maximum UV transmission and protects the bulb
• Designed for optimal flow of 2,000–3,000 GPH to maximize contact time
• Integrates with existing mechanical/biological filters for best results

What size pond and flow rate is this clarifier suitable for?

The Shock Wave 55W is specified for ponds up to roughly 6,000 gallons when paired with appropriate filtration and circulation. Matching the unit to the recommended flow range ensures adequate UV exposure for effective clarification.

• Recommended pond capacity: up to 6,000 gallons with proper filtration
• Optimal flow rate: 2,000–3,000 GPH for best UV contact time
• Graduated barb fittings from 0.75" to 1.5" accommodate common pipe sizes
• Not a substitute for biological balance—use alongside skimmers and biofilters

How is the Shock Wave 55W installed and maintained?

The unit is designed for inline installation between your pump and filter or after the filter, depending on system layout. The durable outer housing and quartz sleeve simplify maintenance; the glowing indicator lets you confirm the bulb is operating at a glance.

• Includes 22-foot total cord and 120V transformer for straightforward power connection
• Easy inline mounting with graduated barb fittings to match plumbing sizes
• Quartz sleeve and bulb are serviceable—replace bulb after roughly 9,000 hours
• Manufacturer offers maintenance videos and a 2-year warranty for support

What safety and durability features should I expect?

The Shock Wave’s rigid 2.5" outer housing protects the internal quartz sleeve and bulb from environmental wear, and the transformer keeps the electrical supply appropriate for safe operation. Visual bulb indicator simplifies monitoring so you can spot failures quickly.

• Robust outer housing for long-term outdoor use
• Quartz sleeve resists water contact with the bulb while allowing UV transmission
• Glowing light indicator for easy operational checks
• Backed by a two-year manufacturer's warranty for parts and workmanship

Who is this for? The HALF OFF PONDS Shock Wave 55W in-line clarifier is intended for pond owners and water-feature enthusiasts who already maintain mechanical and biological filtration and need a reliable UV solution to reduce cloudiness and algae bloom. It’s well suited for medium to large backyard ponds (up to ~6,000 gallons) with pumps capable of 2,000–3,000 GPH; those seeking a plug-and-play inline clarifier with clear maintenance guidance and warranty coverage will find this unit a practical addition to their system.
