QANVEE FX100B Slim Type Sponge Filter
The QANVEE Slim Type Filter provides both mechanical and biological filtration, helping maintain clean and healthy water in your aquarium. Simply connect an airline tube to the unit to receive aeration and filtration. Aerobic bacteria grow within the sponge media, supporting the nitrogen cycle by breaking down harmful ammonia and nitrites.
The slim design saves space and keeps your aquarium looking neat and organized. The sponge effectively traps larger waste particles without capturing small fish or shrimp, making it safe for delicate aquatic life.
You can adjust the filter size to match your aquarium dimensions by combining multiple units for optimal performance.

I installed this filter in my 10-gallon tank and it’s been working well. The slim design fits perfectly without taking up much space. My shrimp and small fish are safe, and the water stays cleaner than before. Easy to set up and maintain.

The filter provides good mechanical filtration and helps with water clarity. I noticed a noticeable improvement in water quality after a week. The airline connection is straightforward and the sponge doesn’t clog easily.

Great for a small tank. It doesn’t trap baby fish, which was a big concern. The biological filtration supports the nitrogen cycle, and the tank looks much neater now.

Works well with my community tank. I combined two units for a larger tank, and it handles the waste efficiently. No issues with fish getting stuck.
