Description

This high-efficiency bulb has an 8,000-hour life, so it should be replaced after 11 months of continuous operation. Make sure to replace every pond season - the bulb may continue to glow, but its effectiveness in killing algae diminishes. Convenient viewing window in Tetra Pond Green Free UV Clarifier makes it easy to ensure the bulb is working. This bulb is 35 watts for ponds up to 8,800 gallons. Tetra Pond Green Free UV Clarifier (not included) works to keep your pond clean, clear, and free of unsightly green algae. These dependable clarifiers use ultra violet 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 Tetra Pond Green Free 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.
