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 free flowing bacteria, yeast, mold and other pathogens, in turn clearing up green water without any chemicals. In addition, the Green Killing Machine’s design allows it to be hidden behind ornaments or plants in your aquarium, eliminating potential leaks around your tank.
