Enhance the beauty of your landscaping and outdoor scenery with the Alpine Corporation 4" tall 7-Watt UV Clarifier. This water clarifier uses ultra-violet rays to control suspended algae with UV light to help you maintain your outdoor water landscaping. The efficient water clarifier ensures 100% clarity in your indoor or outdoor fountains or ponds. Constructed of weather-resistant plastic, the UV clarifier is made tough for outdoor use and is only intended for out of water use. The UV clarifier is easy to use and rotates 360 degrees making it easier to run a hose to and from the unit. As water passes through the rays of an ultra-violet lamp located inside each unit, it cleans green water by making the algae clump together so it can be removed by a pond filter for quick cleaning. The compact UV clarifier measures 13"L x 6"W x 4"H and universal connectors fit 3/4" and 1-1/2" tubing, and includes a two-year manufacturer's Support from purchase date.
