Ultraviolet germicidal irradiation (UVGI) is a proven method that uses short wavelength ultraviolet (UVC) light to kill or inactivate unwanted microorganisms. Many drinking water systems use this technology.
The Green* Killing Machine (GKM) makes fighting green water easier as it is internal UV – that is, a UV system that you simply drop into your tank for a full UV protection.
UV radiation is effective in controlling water contaminants, in turn clearing up green water without any chemicals. In addition, the design of GKM allows it to be hidden behind ornaments or plants in your aquarium, eliminating potential leaks around your tank.
