After the water has been clarified, it is recommended to use the UVC lamp regularly – for example on the first day after a water change or once a week, even without a water change.

Important: The UVC lamp must not be pointed directly at fish, plants, skin, or eyes. The device must be mounted correctly in the water and operated according to the instructions.
