360° Protective Safety Shield: Equipped with a 360-degree protective shield to help block direct U-V exposure, providing added safety for fish and users during operation.

Two Working Modes for Different Setups: Healthy Mode (Shield Closed): Suitable for direct use inside fish tanks; High Efficiency Mode (Shield Open): Recommended for use inside filter chambers for enhanced algae clean.

Complete Accessories: Includes 1× U-V light with timer, 2× suction cups, and user manual. NOTE: When placed directly in a fish tank with fish swimming, the U-V lamp cover needs to be closed to prevent the leakage of ultraviolet rays.

User Instructions: During the green algae outbreak period, the 24H mode can be used continuously for 3 to 7 days. For daily maintenance, it is recommended to use for 3H per day. Long-term continuous 24H operation will shorten the lifespan of the bulb.
