Coralife® 3X Turbo Twist UV Sterilizer 9 Watt 13.5 X 7.825 X 3.75 Inch

Water is pumped into the sterilizer chamber where ultraviolet light eliminates the unwanted microorganisms resulting in a clean and clear aquarium. Coralife Turbo-Twist ultraviolet sterilizers feature a unique twist flow design that guides water flow more evenly through the sterilizer, increasing exposure to ultraviolet light and improving the treatment of unwanted algae and harmful microorganisms.
