Hang on Back Aquarium Filter，Aquarium Filter，Quiet for 5-20 Gal.

Key features

• Adjustable Flow: This filter features adjustable flow rate and surface debris cleaning. 6W, 140 GPH — you can freely adjust the flow. The surface skimmer removes floating debris from the water surface, making it look clearer.
• Efficient filtration design: The water pump delivers water directly into the filter box, ensuring thorough contact between the water and the filter media. This prevents water from merely flowing through certain areas and returning to the tank unfiltered, resulting in better filtration performance.
• Replaceable filter media: The internal filter box is easy to replace. The filter box can be opened to replace or clean the filter media, and you can also add other filter media into the filter box according to your preference.
• Quiet Operation: The motor features a floating design that reduces noise caused by resonance, so it won't disturb aquatic animals.
• Waterfall hang-on filter: Black transparent casing for easy viewing, smooth surface for easy cleaning. 6.0" x 4.5" x 5.9", perfectly fits most aquarium setups.
