Nano Tank Hang on Back Filter

This nano hang on back filter is excellent for aquariums up to 10 gallons. It moves 52 gallons per hour and has an adjustable flow knob for fish who need lower flow such as bettas. It comes fully equipped with media and an intake sponge. However, upgrading to our mini pre filter sponge is ideal as it will offer greater coverage of the intake tube including the bottom. Hot rod this filter by adding coarse sponge to the media portion rather than the provided cartridges.
