Manufacturing Inc., Pondmaster 20-watt Submersible Ultraviolet Clarifier with 1 1/2" Barbed Inlet/Outlet, Black, 02925

The Pondmaster 20 -watt submersible UV Light is a high-performance UV light that controls green water in your pond, making water clarity its top priority. By successfully controlling green water you promote a healthy and thriving aquatic environment. The Submersible 20-watt Ultraviolet (UV) Pond Light is for use with pumps up to 1800 GPH, in medium sized ponds up to 3000 gallons. The vortex flow design increases the exposure time of the water to the ultraviolet light and the slim diameter brings more of the water closer to the intense UV rays making the process even more efficient. These UV clarifiers can be installed submerged in or outside the pond. When the light is submersed, it doesn't detract from the natural pond aesthetics, or its slim design can be tucked behind pond borders for concealed above-surface installation (with proper tubing). Includes Transformer and 18-foot grounded power cord that easily reaches nearby power sources, that is UL listed. Features soft, blue indicator ring lights that show that the unit is on and working. Item 02925 comes with 1 1/2" MNPT Threaded Inlet and Outlet, Complete with 9000 Hour 20 Watt Lamp in Watertight Quartz Sleeve, Includes one pair of 3/4”, 1”, 1 1/2” Stepped Barb Fittings.
