Product Description

This replacement bulb is designed for use in TetraPond GreenFree UV Clarifier for ponds. 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 TetraPond GreenFree UV Clarifier makes it easy to ensure the bulb is working. Replacement bulbs are available in four sizes: 5 watts for ponds up to 660 gallons; 9 watts for up to 1,800 gallons; 18 watts for up to 4,400 gallons; and 36 watts for up to 8,800 gallons. 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. Since 1951, Tetra has developed the world’s most comprehensive body of fish food knowledge, and fishkeeping enthusiasts have looked to the brand for products and solutions that add ease and beauty to their home. Whether you're an experienced hobbyist or just starting out, Tetra has everything you need – from a large variety of quality fish food and innovative equipment to test kits and decor.

TetraPond GreenFree UV Clarifiers Keep Your Pond Clear and Clean

TetraPond 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 is then pumped out of the Clarifier where it clumps and is removed by your tank’s filtration system. Tetra UV Clarifiers can typically remove heavy algae blooms within five days and keep your pond algae-free long term. GreenFree UV Clarifiers are easy to conceal, durable, install in minutes, and feature a 3-year limited warranty.
