COOSPIDER 400GPH Aquarium Filter with 7W UV Light for 284–757 L Tanks

The COOSPIDER internal aquarium filter is designed for 75–200 gallon aquariums and combines a 400GPH water pump with a 7W U-V light.

• Six functions: green clean, oxygen supply, deodorization, wave generation, water circulation and water pumping — supports several aquarium tasks with one internal unit.
• U-V lamp and replaceable filter sponge — combines light-based water treatment with sponge filtration.
• Independent pump and lamp switches — lets you operate each function separately.
• IPX8 waterproof construction — made to run fully immersed in water.
• Detachable, reusable filter cotton — can be rinsed and used again after cleaning.

Murky aquarium water can make routine tank care more demanding. This submersible filter is made for aquariums in the stated capacity range, including fish tanks and turtle tanks, and combines water movement with filtration and a U-V lamp. Its separate controls let you manage the pump and lamp independently.

What does the COOSPIDER aquarium filter do for tank water?

The filter pairs a 7W, 254nm U-V lamp with a high-quality filtering sponge to purify aquarium water. The brand says it can help turn murky water clear within 3 to 7 days and reduce how often aquarium water needs changing; results depend on the aquarium and its conditions.

• The pump is rated at 30W and 400GPH.
• The filter sponge is replaceable and can be cleaned for reuse.
• The unit also supports water circulation, wave generation and oxygen supply.

How do I install and operate the COOSPIDER aquarium filter?

Fully immerse the filter in water, then connect its power cord. The pump and U-V lamp have separate switches, so the lamp does not need to run continuously with the pump.

• The recommended U-V lamp schedule is 1 to 2 hours per day.
• You can check whether the lamp is on from outside the unit.
• The IPX8-rated filter is designed for fully submerged use.

How do I clean the COOSPIDER filter?

The U-V lamp and filter sponge can be disassembled for cleaning, and the filter cotton can be reused after a simple wash. This gives you access to the filter components for routine maintenance without discarding the cotton after each cleaning.

• The sponge is replaceable.
• The lamp and sponge are designed for straightforward removal and cleaning.

The COOSPIDER filter suits aquarium keepers who want an internal, fully submerged unit for a 75–200 gallon fish or turtle tank, with a pump, sponge filtration and a U-V lamp in one system. Its separate controls, reusable filter cotton and six listed functions make it a fit for buyers seeking combined water movement and filtration in a single aquarium filter.
