24W Green Killing Machine Internal UV Sterilizer with Power Head

The Green Killing Machine 24W Internal UV Steriliser is an all-in-one solution for maintaining clear and healthy aquarium water in tanks up to 450 litres. Combining a UV steriliser with a built-in powerhead, it allows water to pass directly over the UV lamp for effective treatment of algae and water clarity issues.

Designed for straightforward installation, the unit comes fully submersible and mounts securely inside the aquarium using suction cups. Setup takes only a few minutes with no tools required. The integrated LED indicator alerts you when the UV bulb needs replacing, and the sealed bulb design means each replacement refreshes the unit’s internal components.
