UV Clarifiers & Bulbs

UV clarifiers are a common way for the pond owner to keep their pond water clear. Excess nutrients in the water can lead to a green water algae problem. A UV clarifier works by passing the water through a tube next to a UV bulb. The high intensity light kills off the microscopic algae cells that form green water. The bulbs need replacing every so often (approximately once per year), here you can see our full range of replacement bulbs for standalone clarifier units as well as for those filters that come with a build in clarifier.
