hygger 12W Aquarium Internal Filter for 56.8–114 L Tanks with UV Timer, 200 GPH

The hygger 12W Aquarium U-V Internal Filter combines sponge filtration, UV light, oxygenation and water circulation for 15–30 gallon aquariums, with a maximum flow of 200 GPH.

• Four functions in one filter — filter water, support oxygenation, help clear green water and circulate water.
• 12W power and up to 200 GPH flow — made for aquariums sized 15–30 gallons.
• Separate pump and UV light switches — run filtration with the UV light off when preferred.
• UV timer choices of 4, 8, 12 or 24 hours — choose a lamp runtime for your use.
• Two water outlets — select aeration or rainfall-style water distribution.
• Filter, pump, UV light and accessories included — the set contains the components for both outlet modes.

Cloudy or green aquarium water can make it harder to enjoy a clear view of the tank. This internal filter pairs a sponge that catches residue and other impurities with a UV lamp, while its pump moves water and the outlets provide options for oxygenation and circulation. It is made for freshwater and saltwater aquariums within its stated capacity.

What does this aquarium filter do?

The hygger filter brings together mechanical filtration, UV illumination, oxygen support and water movement in one internal unit. Water passes through the sponge, which filters out residues and other impurities. The UV lamp irradiates the water to help keep it clear and transparent; the plastic housing and sponge are designed to prevent light leakage and create a safe environment for fish.

For cloudy or green water, the product guidance gives a clearing timeframe of 3–8 days, depending on tank size and water quality. For a green-water problem, it recommends running the UV light for 24 hours a day for 3–5 consecutive days. For routine maintenance, the recommended UV runtime is 4 hours daily.

• Includes an observation window for checking whether the UV light is working.
• The sponge filters residue and other impurities from aquarium water.

How can I choose between the two water outlets?

The hygger filter offers an aerating mode and a rainfall mode, each with a different way to move water. In aerating mode, an air venturi and adjustable tubing boost oxygen levels. In rainfall mode, a spray bar disperses filtered water evenly across the tank, creating gentle surface agitation and supporting circulation.

Choose the outlet arrangement that suits the water movement you want in your aquarium. The aerating setup uses the included air hose, while the rainfall setup uses the included rain shower pipe. Both options work alongside the filter’s water-circulation function.

• Aerating mode: air venturi and adjustable tubing.
• Rainfall mode: spray bar for even water distribution and gentle surface agitation.

Can I control the pump and UV light separately?

Yes. The hygger filter has independent controls for the water pump and UV light, so you can keep the filtration function running while switching the lamp off. The timer controller offers 4-, 8-, 12- and 24-hour UV light settings.

This separate control lets you choose the lamp runtime for your aquarium instead of having the UV light operate whenever the pump is on. Use the 24-hour setting for the consecutive-day green-water guidance, or the 4-hour setting for the stated daily maintenance routine.

• Water pump and UV light have separate switches.
• Timer options: 4, 8, 12 or 24 hours.

What size tank and accessories does it suit?

The hygger internal filter is designed for 15–30 gallon tanks and has a maximum flow rate of 200 GPH. It is suitable for freshwater and saltwater aquariums. Compare your aquarium’s capacity with that range when choosing this filter.

The package contains one filter with sponge, one pump with power cord, one UV light with timer controller, four suction cups with base, one rain shower pipe and one air hose. These components provide the filter, pump, timed UV control and parts for the two outlet modes.

• Tank capacity: 15–30 gallons; maximum flow: 200 GPH.
• Included parts: filter and sponge, pump and power cord, UV light and timer controller, four suction cups with base, rain shower pipe and air hose.

This filter is suited to aquarium keepers who want filtration, UV illumination, oxygenation and water circulation in one unit, with separate pump and lamp control and a choice of outlet style. Its 15–30 gallon capacity, included aerating and rainfall components, and selectable UV timer make it a fit for freshwater or saltwater tanks in that range.
