hygger 25W Aquarium UV Internal Filter for 114–492 L Tanks with Timer, 450 GPH

The hygger 25W UV internal aquarium filter is designed to filter aquarium water, support oxygenation and circulation, and help clear green water, with a maximum flow of 450 GPH.

• Fits 30–130 gallon tanks — choose it for aquariums within this capacity range.
• Four functions in one filter: filtration, oxygenation, green-water cleaning and water circulation — supports several aquarium needs with one unit.
• Independent pump and UV-light controls with 4, 8, 12 or 24-hour timer settings — run the light on a schedule that suits your use.
• Two outlet options — choose aeration or spray-bar water distribution.
• Sponge filtration and a UV lamp — filter residues and impurities while helping clear green water.

Cloudy or green aquarium water can make it harder to enjoy a clear view of the tank. This internal filter combines mechanical sponge filtration with a UV lamp, while also moving and oxygenating water. It is made for freshwater and saltwater aquariums, with selectable light timing for targeted use or daily maintenance.

Can this filter help with cloudy or green aquarium water?

Yes. The hygger filter uses a sponge to capture residues and other impurities, while its UV light is designed to help clear green water. The stated clearing time is 3–8 days and depends on tank size and water quality, so results can vary.

For heavy green-water conditions, the recommended UV-light schedule is 24 hours a day for 3–5 consecutive days. For daily maintenance, the suggested setting is 4 hours. The light has a plastic shell and sponge that help prevent light leakage, and an observation window lets you monitor whether it is working.

• Choose a 4, 8, 12 or 24-hour timer setting.
• Run the pump without the UV light when filtration is needed without UV operation.

How can I control oxygenation and water movement?

The filter provides two outlet modes: aerating mode and rainfall mode. Aerating mode uses an air venturi with adjustable tubing to boost oxygen levels, while rainfall mode sends filtered water through a spray bar for even distribution.

The spray-bar flow creates gentle surface agitation and supports circulation around the aquarium. Select the outlet style that suits the way you want water to move; the pump and UV light can also be switched independently.

• Air venturi and adjustable tubing for aeration.
• Rain shower pipe for spray-bar distribution.

What tank size and aquarium type is it made for?

This hygger internal filter is intended for 30–130 gallon aquariums and can be used in freshwater or saltwater tanks. Its maximum flow rate is 450 GPH, and the 25W unit combines water filtration with circulation and oxygenation functions.

Use the tank’s gallon capacity to check fit before choosing this filter. The water-clearing timeframe can vary with tank size and water quality, so the suggested schedule is a guide rather than a guaranteed result.

• Suitable for freshwater and saltwater aquariums.
• Includes four suction cups with a base to hold the filter in place.

What comes with the hygger aquarium filter?

The set includes the filter with sponge, a pump with power cord, and a UV light with timer controller. It also comes with four suction cups with a base, a rain shower pipe and an air hose, giving you the listed components for filtration, timer control and either outlet mode.

The sponge handles residues and other impurities, while the UV light is housed behind a plastic shell and sponge to help prevent light leakage. The observation window provides a way to see the light’s working condition without relying only on the timer settings.

• Filter with sponge and pump with power cord.
• UV light with timer controller, four suction cups with base, rain shower pipe and air hose.

This filter suits aquarium keepers who want one internal unit for sponge filtration, water movement and oxygen support, with UV-light timing available separately from pump operation. It is made for freshwater and saltwater tanks within the 30–130 gallon range, with two outlet modes and included accessories for both aerating and spray-bar use.
