AlgClear UVC 20000 / 18 W

Additional information: UVC-devices ensure clear water in garden ponds, as their UV-radiation kills the algae germs that are reponsible for algae formation. When it enters the UVC-device, a spiral makes the water circulate around the outside of the casing around the UVC-crystals, so that the water is treated with the radiation for longer, therefore increasing efficiency. The AlgClear 20000 UVC is suitable for the following pond sizes: 10000 litres without fish, 5000 litres with fish.
