The Coralife Turbo Twist 12X UltraViolet Sterilizer, 36W, features 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 micro-organisms. Requires a powerhead that will provide an approx. 400 to 1200 gph flow rate. The Rio 14HF HyperFlow Powerhead is a good choice. Can be used with 3/4", 1" or 1-1/4" hose. Hose is not included. The amount of hose depends on how you set up your Turbo Twist—about 6 feet of hose is what most people use. For aquariums up to 500 gallons. Dimensions: L 23.375" x W 10.75" x H 5".
