The Green Killing Machine (GKM) makes fighting green water easier!
It is an internal UV filter with a power head that you can simply drop into your tank for full UV protection.
In addition, the design allows it to be hidden behind ornaments or plants in your aquarium, eliminating potential leaks around your tank.
UV Filters help eliminate green water, cloudiness and reduce water changes.
Additional features: • Water pump included. • Simple installation. • Submersible assembly. • No external pipes or plumbing. • Suction cup mounting - no hardware required. • LED signals need for UV bulb replacement. • Unique technology. • Replacement bulbs are available separately.
