AA Aquarium Green Killing Machine Internal UV Sterilizer; Available in 2 sizes

AA Aquarium Green Killing Machine makes fighting green water easier. UV radiation is effective in controlling bacteria, yeast, moulds, and other pathogens, in turn controlling algae growth. Water flows in direct contact with the UV lamp, intensifying its function of fighting green water. In addition, it can be hidden behind ornaments in your aquarium, cutting back on tubing around your tank. The Green Killing Machine is available in a 9 watt (ideal for aquariums up to 50 gallons), and 24 watt (ideal for aquariums up to 100 gallons). The UV Sterilizer Kit comes with UV sterilization lamp sealed in quality plastic enclosure, filtration pump complete with filtration sponge, safety approved power adaptor, control box with UV bulb replacement LED indication, and easy assembly-no tools-suction cup mounting.
