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

Danner Manufacturing, Inc., Pondmaster Ultraviolet Clarifiers safely control free-swimming “suspended” algae without the use of any chemicals or water treatments. “Suspended” pond algae causes your pond water to become green and cloudy. Pondmaster Ultraviolet Clarifiers help maintain crystal clear water in your pond by passing it in a spiral motion across the UV Lamp mounted inside the housing, greatly reducing the algae levels in your pond. They be used either fully submerged or out of the water and feature a glowing monitor Halo Ring that shows the clarifier is working. The soft blue Halo is visible during the day or at night from any angle, but does not detract from the beauty of your pond. Pondmaster Ultraviolet Clarifiers are designed to handle the clarifying needs of ponds up to 3,000 gallons. One of the simplest and safest ways to keep your pond water clean and clear is to install a UV Clarifier.

• 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.
