hygger 4-in-1 Aquarium U-V Filter with Sponge, Light & Timer for 10-20 Gallon Tanks

Meet hygger’s compact 4-in-1 Aquarium U-V Filter, a versatile internal unit that blends filtration, aeration, algae control, and water circulation in a single, easy-to-install system for small to mid-sized tanks. It’s designed to fit 10-20 gallon setups and operates with efficiency and reliability, helping you create a healthier aquarium environment without taking up valuable space.

Powered by an 8W pump with a capable flow of up to 132 GPH, this filter moves water confidently to maintain turnover and surface activity. The integrated UV-C lamp helps improve water clarity by reducing visible residues, while the durable shell and sponge media minimize light leakage to keep the tank visually calm for your fish and plants. This combination of filtration, light, and circulation is built into one compact package that can be managed with simple controls.

Independent controls for custom setups

• Separate switches let you run the filtration and UV light on your schedule.
• Choose from timer options for the UV light (4, 8, 12, or 24 hours) to fit your routine.
• Easy access observation window lets you monitor the light’s status without disassembly.

Two oxygenation modes for flexible water care

• Aerating mode uses an air venturi and adjustable tubing to boost dissolved oxygen.
• Rainfall mode disperses water via a spray bar for gentle surface agitation and improved circulation.

Clear water, simple maintenance

• Effective filtration plus UV-assisted clarity helps tackle cloudy or green water trends over days.
• All-in-one design includes filter media sponge, pump with power cord, UV light with timer controller, four suction cups with bases, a rainfall shower pipe, and an air hose for complete setup.

What you get is a user-friendly, compact solution for freshwater and saltwater tanks that can help support routine maintenance and a stable aquatic environment. While individual results vary, many hobbyists notice clearer water and healthier surface movement after a few days of use. The complete package is ready to install, with an observation window to easily verify the UV lamp’s working condition and keep your setup running smoothly.
