hygger 3W Aquarium U-V Light with Timer for 2-15 Gallon Fish

• Clean Green Water: hygger aquarium U-V light adopts a 254nm wavelength designed to help clean green water buildup in aquariums. This U-V light clarifier improves water clarity and supports a cleaner aquatic.
• Small & Space-Saving Design: Designed for 2–15 gallon fish tanks and turtle tanks. The compact structure fits easily into tight spaces without affecting the aquarium layout. A sealed protective cover helps direct U-V exposure while allowing light to emit mainly from the back for easy operation checks. To minimize eye exposure, place the back light side close to the tank back wall or near the bottom of the aquarium.
• 4 Timer Modes with Memory Function: Built-in controller timer offers 4H / 8H / 12H / 24H settings for convenient daily use. Once selected, the U-V lamp automatically repeats the cycle every day and remembers the last setting after power interruptions.
• Easy Installation & Better Cleaning Performance: Aquarium clean light can be used directly in fish tanks or turtle tanks, but works best in moving water or filtration systems. For optimal results, place the lamp near the filter flow or use with a wave pump to improve circulation and cleaning efficiency.
• Crystal Clear Water in 3–7 Days: Helps clear cloudy and water within days depending on tank size and water condition. Recommended to run continuously for 3–5 days during severe green water outbreaks, then switch to 4-hour daily maintenance. Safe for freshwater and saltwater aquariums with no impact on fish health when used properly.
• NOTE: Do not expose the U-V light directly to people, fish, reptiles, or plants. For best results and safety, use the U-V light inside a filter system or attach it to the back wall or bottom of the tank.
