Murky aquarium water can make tank upkeep more demanding. This submersible filter combines UV light and a replaceable filter sponge to support water cleaning, while its pump circulates the tank water. It is made for fish and turtle tanks within its stated capacity range, with multiple water-management functions in one internal unit.

How does the COOSPIDER aquarium filter clean water?

It combines a UV light with a replaceable filter sponge to help purify aquarium water. In a 30–100 gallon (114–379 L) tank, it can turn murky water clear within 3–7 days; the claimed result is also intended to help keep water fresh longer and reduce water-change frequency. Its six functions cover green-water cleaning, oxygen supply, deodorization, wave generation, circulation and pumping.

• The sponge can be removed, cleaned and reused.
• The UV light and filter sponge are designed to be taken apart for cleaning.

What tank size and setup is this filter made for?

The COOSPIDER internal filter is intended for aquariums from 30 to 100 gallons (114–379 L), including fish and turtle tanks. Place the unit fully underwater and connect its power cord to run the pump. The IPX8 waterproof design is made for submerged use.

• Compare your tank capacity with the 30–100 gallon range before choosing.
• The 11W pump and 5W UV light are built into the filter unit.

How do the pump and UV light operate?

Separate switches let you control the water pump and UV light independently. The recommended UV-light use is 1–2 hours per day rather than continuous 24-hour operation. You can see from outside the unit whether the UV light is on, without opening the filter.

• Immerse the filter completely before connecting its power cord.
• Clean the reusable filter cotton by removing and washing it.

This COOSPIDER filter suits aquarium and turtle-tank keepers who want a submersible unit that combines water circulation with UV light and reusable sponge filtration. Its stated 30–100 gallon capacity, independent controls and six water-management functions make its intended fit clear.
