Fluval's Underwater Filter is an optimal water filtration system for aquariums. Equipped with foam filter media, it helps to provide effective and thorough mechanical and biological filtration. A fine foam pad traps small debris while a bio-foam captures debris and nitrifying bacteria. The nano filter has adjustable output with an attachable spray bar that distributes a gentle, even flow of water, making it safe for delicate fish or shrimp. This is also great for use with aquatic turtles and terrestrial turtles.
