What is a uv light and how does it work?
UV is short for Ultra Violet. A UV sterilizer or clarifier is a light unit that emits UV rays. As water passes through the light, living organisms such as algae are destroyed. The wattage output of the UV light and the speed at which the water passes through it are critical to its performance. Be sure to match the size of the UV light to the size of your pond (total gallons) and regulate the flow through the light for the best results.
