Tetra GreenFree UVC36 Pond Clarifier (MPN 19522)

Tetra Pond UV Clarifiers are the perfect solution for eliminating unattractive green water algae and maintaining a clear and pristine pond. These clarifiers use ultraviolet light to destroy the ability of single cell algae to reproduce, effectively getting rid of the dreaded "pea soup" appearance. Additionally, these clarifiers feature a mechanical safety switch that automatically turns off the bulb when the ballast is removed. To ensure optimal performance, it is recommended to change the UV bulb once a year, preferably in early spring to take advantage of the strongest output during the peak of pond season sunshine. Installation is simple as the clarifier is placed outside the pond and inline with the tubing. With a 15' power cord, it provides flexibility in terms of placement. The process is straightforward - the UV light eradicates the ability of single-cell algae to reproduce, causing them to die and clump together. These clumps can then be easily removed by filtration, leaving your pond clear and free from green water.
