Fluval Nano Aquarium Filter is an optimal water filtration system for small aquariums up to 55 litres (15 US gal). 

Equipped with foam filter media, it provides effective and thorough mechanical and biological filtration. A fine foam pad traps small debris and a Bio-Foam captures debris and houses nitrifying bacteria. The filter also provides the option of adding a carbon cartridge (sold separately) for additional chemical filtering.

The Nano Filter has an adjustable flow output with an attachable spray bar that distributes a gentle, even flow of water, making it safe for delicate fish or shrimp.
