hygger Aquarium UV Internal Filter, 8W for 37.9–75.7 L Tanks with Timer

The hygger Aquarium UV Internal Filter combines sponge filtration, UV light, oxygenation, and water circulation for aquariums holding 10–20 gallons (38–76 L).

• 8W power and a maximum flow rate of 132 GPH (500 L/h) — moves filtered water through the aquarium.
• Four functions: filtration, oxygen increase, algae cleaning, and circulation — addresses several water-care needs with one filter.
• Separate pump and UV light controls — lets you run filtration without switching on the UV lamp.
• UV timer settings of 4, 8, 12, or 24 hours — allows you to select a lamp operating period.
• Two water outlets — choose aeration or rainfall-style water distribution.

This internal filter is made for aquarium owners who want to filter debris, address cloudy or green water, and keep water moving while adding oxygen. Its functions suit freshwater and saltwater aquariums within the stated capacity range.

How does the hygger filter help with cloudy or green water?

The hygger Aquarium UV Internal Filter combines a sponge with a UV lamp to filter residues and other impurities while irradiating the water. The sponge performs the physical filtration, while the UV light is intended to help keep aquarium water clear; the plastic housing and sponge also help prevent UV light from leaking out. Clearing cloudy or green water may take 3–8 days, depending on tank size and water quality.

For a heavy green-water episode, the recommended lamp schedule is 24 hours a day for 3–5 consecutive days. For routine maintenance, the recommended operating time is 4 hours daily. These are guidance for using the UV light, not guaranteed clearing times.

• The included observation window lets you monitor whether the UV light is working.
• The sponge captures residues and other impurities from the aquarium water.

Can I run the filter without the UV light?

Yes. The pump and UV lamp have independent switches, so you can use the aquarium filtration function with the UV light turned off. The timer controller offers 4-, 8-, 12-, and 24-hour options for setting the UV lamp’s operating period.

This separate control is useful when you want water filtration to continue without operating the lamp. Select the timer period according to the intended use: the recommended daily maintenance schedule is 4 hours, while a heavy green-water episode calls for 24 hours for 3–5 consecutive days.

• The UV lamp has its own timer controller.
• Use the observation window to check the lamp’s working condition.

How can the filter add oxygen and circulate water?

The hygger filter provides two outlet options: aerating mode and rainfall mode. Aerating mode uses an air venturi and adjustable tubing to increase oxygen in the water. Rainfall mode sends filtered water through a spray bar, distributing it across the surface to support gentle agitation and circulation.

Choose the outlet arrangement that suits how you want water movement and oxygenation delivered in your aquarium. Both modes use the filter’s water flow, while the aerating setup adds air through the venturi and tubing.

• The package includes one rain shower pipe for rainfall-style output.
• An air hose is included for the aerating setup.
