Tetra GreenFree® UVC


GreenFree® UVC

Product Details

Dependable clarifiers use ultraviolet light to destroy the reproductive ability of suspended algae. Dead algae clump together in particles large enough to be removed by filtration,leaving the pond clearer.

GreenFree® clarifiers usually remove heavy algae blooms within five days and keep the pond algae-free. New design prevents quartz sleeve being damaged from incoming dirt in the water flow and spiral feature allows water to stay longer in the unit for greater UV exposure. They are easy to conceal, durable, and install in minutes.
