QiQiWader Fish Tank Filter — 6W, 130GPH, Adjustable Aeration for 10–40 Gallon Tanks

Effortless, all-in-one filtration for your freshwater setup

QiQiWader's submersible filter combines mechanical filtration, water movement, and oxygenation in one compact unit. The built-in control knob lets you fine-tune the amount of oxygen introduced into the water, so you can match the daily needs of your aquarium.

Two-stage filtration that balances clarity and health

The dual filtration system includes a bio sponge that traps debris and uneaten food to help keep water clearer. It also features bio-media balls that foster beneficial processes, helping convert ammonia and nitrite into less harmful nitrate and supporting a stable environment.

Designed for 10 to 40 gallon tanks

With 6 watts of power and a flow of 130 gallons per hour, this filter suits mid-sized tanks. If your setup differs significantly from the recommended range, consider a model tailored to your tank.
