Oceanic 36011 BiocubeMini Ultraviolet Sterilizer, 5-Watt
Oceanic BioCube Mini Ultraviolet Sterilizer kills free-floating algae, parasites and other harmful bacteria as water passes over the UV bulb, making it cleaner, clearer and safer for your aquarium fish. Designed to fit inside the aquarium, the Mini Ultraviolet Sterilizer attaches directly to the built-in BioCube pump for ease of setup and use. This mini sterilizer fits BioCube sizes 14 and 29, but with the included universal adaptor you can also use it in other small aquariums. The kit includes a 5-watt ultraviolet lamp. To maintain function of your BioCube Ultraviolet Sterilizer you should replace the lamp every 6 months.
