TetraPond GreenFree UV Clarifier (not included) works to keep your pond clean, clear, and free of unsightly 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.
