Shock Wave UV In-Line Ultraviolet Clarifier

Keep your pond clean and clear with the Half Off Ponds Shock Wave UV In-Line Ultraviolet Clarifier. It’s an essential addition to any pond or water garden filtration system. Paired with your mechanical and biological filtration, it treats water as it flows through the unit. Most ponds show results in as little as 3–5 days, and larger water features may take about a week. Four wattages are available to match your pond: 9-watt: ponds up to 900 gallons at 300–500 GPH 18-watt: up to 2,000 gallons at 500–1,200 GPH 36-watt: up to 4,000 gallons at 1,200–2,400 GPH 55-watt: up to 6,000 gallons at 2,000–3,000 GPH The rugged injection-molded ABS outer housing is built for years of reliable operation. It also cuts down on the maintenance and cleaning your water feature needs. Each UV bulb lasts up to 9,000 hours before it needs replacing, and a glowing indicator lets you check that the bulb is on. Every system includes a 2.5" diameter outer housing, quartz sleeve (glass tube), UV bulb, 120-volt transformer and 22-foot total electrical cord. Graduated insert barb fittings from 0.75" to 1.5" make in-line installation easy, and assembly instructions, images and videos guide you through setup. It costs little to run each month, replacement parts are available, and online maintenance videos help keep your system running. Every Shock Wave clarifier has a 2-year manufacturer’s warranty.
