Danner UV Clarifier/Sterilizer

The vortex flow design forces water to spiral around the UV lamp rather than passing straight through. This increases the contact time between the water and the ultraviolet light, which significantly improves the unit's ability to eliminate algae and clarify your pond water.

No, this specific model is designed to be fully submersible. It relies on the surrounding water to help dissipate heat during operation, so it must be placed directly inside your pond or water feature.

You do not need to pull the unit out to check it. The device features a glowing monitor ring that provides a visual indicator, allowing you to confirm at a glance that the lamp is active and functioning correctly.

The included lamp is rated for a 9000-hour lifespan. Depending on your climate and how many hours a day you run the unit, you should generally plan to replace the bulb once per season to maintain peak sterilization efficiency.

The unit is designed for a 1-inch hose diameter. You will need to ensure your existing pump setup is compatible with this size, or have the appropriate adapters on hand to connect the tubing securely.
