The Pond Guy UltraUV 13 Watt Ultraviolet Pond Water Clarifier — EPA Registered UVC Light for Planktonic Algae & Green Water Treatment, Chemical-Free, Safe for Plants, Koi Fish, Ducks, Turtles & Aquatic Life

Keep pond water clear through every season with The Pond Guy UltraUV 13 Watt Ultraviolet Pond Water Clarifier. This EPA-registered UVC unit targets ultrafine planktonic algae that cause green water by exposing them to ultraviolet radiation, which breaks down the algae’s cellular walls. Its rugged vortex chamber forces incoming water to swirl around the UV bulb multiple times for maximum exposure before the water is sent to a biological filter or returned to the pond, producing visible improvement in as little as 48 hours. Chemical-free and safe for pond plants, koi fish, ducks, turtles, and other aquatic life. Note: UV clarifiers must be paired with a properly sized pump for effective operation.
