AQCO EASY FLOW SPONGE FILTER SM

Air collar makes smaller bubbles for improved performance
Easy Flow accessory increases water circulation
Coarse, anti-clogging sponge
Sponge filters offer reliability and hassle-free operation. With no moving parts, all you need is an air pump with some airline tubing, and you've got a filter that is fully contained within your aquarium.  Sponge filters are completely reusable, don't need any replacement cartridges, and last for several years. Plus, they are gentle enough for betta fish, baby fry, shrimp, and other slow-moving species. Trusted by fish farms and wholesalers, they are an excellent choice for aquarium filtration that you can set and forget.
Directions/Specifications
Adjust the height of the Easy Flow curved tube so that the opening is 1/3 out of the water and 2/3 in the water.

Additional Supplies Needed
The sponge filter does not produce air on its own, so you also need to buy the following components to run the sponge filter:
- Air pump
- Airline tubing
- Check valve (to prevent water from pouring out of the tank when the power is off)
