UV Sterilizers: Aqua Ultraviolet
We carry a wide variety of Aqua Ultraviolet UV Light Sterilizers (Ultra Violet Sterilizers) for ponds and aquariums. The Advantage and Advantage+ Aqua Ultraviolet Sterilizers are an easy to install hang-on Aqua UV light for small to medium aquariums. For ponds we recommend using the Aqua UV Sterilizers with 2" connections and for aquariums using the sterilizers with 3/4" connections. The Aqua Ultraviolet Twist UV Sterilizers offer a unique design. A union in the body allows you to rotate the inlet and outlet to the optimum places for your particular hookups. An expansion union included with each Twist UV will allow you to connect additional UV sterilizers to your Twist UV.
