Tetra TetraPond GreenFree UV Ultraviolet Pond Light Clarifier Submersible 18 Watt Making how to get rid of pond algae for good possible! GreenFree UV Clarifiers work to keep your pond clean, clear, and free of green algae. These dependable clarifiers use ultraviolet light to destroy suspended green algae. As algae are pumped into the Clarifier they are exposed to Ultra-Violet light that destroys the reproductive ability of single-celled algae.   The dead algae are then pumped out of the Clarifier where it clumps and is removed by your pond's filtration system. Tetra UV Clarifiers can typically remove heavy algae blooms within five days and keep your pond algae-free long term. Used for up to 4,400 gallons.   GreenFree UV Clarifiers are easy to conceal, durable, install in minutes, and feature a 3-year limited warranty.
