Ultraviolet lights are a safe and effective method of quickly controlling green water algae and bacteria in your pond or large aquarium. The Lifegard Aquatics Pro-MAX UV sterilizer is compatible with both fresh and salt water, and additionally equipped with a white internal reflective sleeve, which increases the efficacy of the UV filtration.
Features a unique flow-through design with less restrictive angled inlet and outlets, requiring less plumbing. The included UL listed ballast also has a display which counts down the number of days until changing the bulb is required.
