Product Description ------------------- TetraPond GreenFree UV Clarifier works to keep your pond clean, clear, and free of unly green algae. These dependable clarifiers use ultraviolet light to destroy suspended green algae. As algae are pumped into the clarifier, they are exposed to ultraviolet light that destroys the reproductive ability of single-celled algae. The dead algae are then pumped out of the TetraPond GreenFree UV Clarifier, where they clump and are removed by your pond's filtration system. Removes heavy algae blooms (usually within 8 days) and keeps the pond algae-free long-term. TetraPond GreenFree UV Clarifier is durable, easy to conceal and installs in minutes. Comes with a high-efficiency bulb for up to 11 months of continuous operation and a high-clarity quartz glass tube. A viewing window makes it easy to ensure the UV bulb is working. Includes ¾ inch, 1 inch and 1 ¼ inch ID tubing adapters, as well as a 15 foot power cord. UL Listed. Features a 3-year limited warranty – see product packaging for details. Replacement bulbs available – replace every pond season (the bulb may continue to glow, but its effectiveness in killing algae diminishes).
