UV-Clarifiers are used to kill algae along with most disease organisms. Water flows through the clarifier but does not harm the beneficial bacteria that grow in filters and on rocks, etc. in the pond. They kill the organisms that are floating in the pond water. (They are not effective on Blanket weed also known as String Algae.)

Ultraviolet energy is unmatched in its efficiency, simplicity and dependability for purifying water. Ultraviolet energy is radiation produced by low pressure mercury lamps. The lamps are made of special glass that allows the passage of UV light rays. This radiation is capable of killing all micro-organisms that it come in contact with. UV rays strike bacteria, algae and protozoa, breaking through the organism's outer membrane. The radiation reaches the DNA of the organisms, causing abrupt modification and bringing about their destruction quickly and effectively. A UV clarifier is the only guaranteed method for complete elimination of pond "green water" algae. Green water algae is forced through the UV sterilizer by the pump at the recommended flow rate. Inside the UV the green water algae is exposed to UV energy, which efficiently destroys it. When properly installed, the dead algae passes with the water out of the UV clarifier into an appropriate filter where much of it is trapped. Upon installation, the
UV completely clears the pond of green water within 3 to 5 days. With continuous operation the UV maintains constant green water elimination. Each unit comes with complete installation and operating instructions.

Did you know??? Most UV manufacturers recommend replacing the bulb annually. Ultraviolet rays will diminish after prolonged use. Just because it lights up does not mean it is still emitting UV rays.
