Tetra GreenFree UVC5 Pond Clarifier (MPN 19523)

Tetra Pond UV Clarifiers are the perfect solution for eliminating green water algae and maintaining a clear pond. These clarifiers use ultraviolet light to destroy the ability of single cell algae to reproduce, resulting in the elimination of green water. This type of clarifier features a mechanical safety switch that automatically turns off the bulb when the ballast is removed. It is recommended to change the UV bulbs once a year, preferably in early spring to maximize the output during the peak of pond season sunshine. These UV clarifiers are designed to be installed outside the pond and in-line with tubing. They come with a 15' power cord for convenient installation. Once the single-cell algae is destroyed by the UV light, it clumps together and can be easily removed by the pond's filtration system. With Tetra Pond UV Clarifiers, you can enjoy a crystal clear pond and say goodbye to unsightly green water algae.
