hygger U-V Light with Timer for 13-40 Gal Aquariums (5W)

Meet the hygger U-V Light with Timer, a compact 5W lamp designed for 13-40 gallon freshwater and saltwater aquariums. The built in UV treatment operates at a 254 nm wavelength to promote clearer water and can help reduce common algae and green water concerns for hobbyists. While results depend on tank conditions, many hobbyists find that the light works best when used as part of a regular maintenance routine rather than as a guaranteed fix.

Four timer modes with memory

• Choose from 3 hours, 6 hours, 12 hours or a full day 24 hours of operation.
• The unit remembers the last setting for quick daily use.
• Simple power switch lets you adapt the schedule as needed.

Safety shield and operation modes

• 360 degree protective shield provides a safer environment around the lamp and tank.
• Healthy mode with the shield closed is designed for placement inside the tank.
• High Efficiency mode with the shield open is suitable near the filter area for enhanced exposure.

What you get and compatibility

• Includes 1 UV light with timer, 2 suction cups and a user manual.
• Replacement bulbs HG245 are sold separately and designed to fit this item.
• Compatible with freshwater and saltwater setups for versatile use.

Usage guidance

During algae outbreaks you may run the 24H mode continuously for a few days to 3 to 7 days. For daily maintenance a shorter 3H cycle can be used. Long term 24H operation can shorten bulb life.

Practical tips for best results

• Place the light in positions that optimize water flow and avoid direct intense glare on fish.
• Use in combination with regular tank maintenance for clearer water and balanced algae growth.

Overall, the hygger U-V Light with Timer offers flexible control, a safety focused design and a set of accessories that can support regular algae monitoring and water clarity in a range of tank sizes.
