hygger 7W UV Light with Timer for 30-130 gal Tanks | Algae Control & Water Clarity

Clearer water and smarter setup

The hygger 7W UV Light with Timer is a compact UV-C lamp designed for freshwater and saltwater aquariums ranging from 30 to 130 gallons. Operating at a 254 nm wavelength, it is designed to help address green water and algae buildup, contributing to crisper water and a clearer view of your aquatic inhabitants. While results can vary by system, many hobbyists notice a more transparent tank during routine maintenance and after targeted algae management periods.

Designed for flexible placement, this unit adapts to different configurations, whether mounted inside the tank or tucked into a filter chamber. The result is a streamlined addition that can fit cellars, cabinets, and stand setups without crowding the workspace. The experience is about cleaner water, easier observation, and a more inviting underwater display.

Key features at a glance

• Four timer modes with a memory function: 3H / 6H / 12H / 24H, with last settings preserved after power interruptions.
• 360° protective shield for safer operation and reduced direct UV exposure.
• Two working modes to suit different layouts: Healthy Mode (shield closed) for direct tank use; High Efficiency Mode (shield open) for filter chambers.
• Complete accessories: UV light with timer, two suction cups, and a user manual; note about shield position to prevent UV leakage when used inside tanks with swimming fish.

Usage guidance helps you balance effectiveness with equipment longevity. During green water outbreaks, the 24H setting can be used for a short, intensive period (3–7 days). For routine maintenance, a brief daily run of 3 hours is typical, since long, continuous operation may shorten bulb life over time.

What makes it a practical choice

• Versatile for 30–130 gallon systems, suitable for both freshwater and saltwater setups.
• Safety-forward design with a 360° shield reduces exposure and supports safer handling around aquatic life.
• Flexible installation options let you optimize space and accessibility in your cabinet or tank.
• Comes with essential mounting hardware for quick setup and ongoing maintenance.

Note: This product is designed to support water clarity and algae management alongside regular tank maintenance. It is not a medical device and is intended to complement established aquarium husbandry practices.
