Tetra GreenFree UV Pond Water Clarifiers

on Clarifier

Eliminate unsightly green water algae and maintain a crystal clear pond with Tetra Pond UV Clarifiers. Ultraviolet light destroys single cell algae's ability to reproduce, eliminating green water (pea soup). A mechanical safety switch automatically turns bulb off when the ballast is removed. Change UV bulbs once a year, best in early spring so you get the strongest output during the peak of pond season sunshine. Installs outside the pond, inline with tubing. 

If your UV Clarifier is appropriately sized, expect water clarity within 14 days. Note that string algae on the waterfall, in the pond, and on the sides won't be impacted by the UV light. This is typical for ponds, as the UV only targets single-celled algae that can pass through the unit. Keep in mind, your pond might retain a greenish tint unless you have at least 50% plant coverage or your pond is in partial shade.
