Quiet Aquarium Hang-On Filter for 21 Gallon Tanks

Multi-Stage Filtration & Oxygenate

Our aquarium filter is designed with three levels of filtration—mechanical, chemical, and biological—to maintain a clean and healthy aquatic environment. This unique combination ensures optimal water clarity and fish health.

Innovative Cleaning Power

The filter's innovative bottom-up-bottom-up water flow design ensures that water contacts all media, providing superior filtration. The extra large filter chamber allows for additional media if needed.

Quiet Operation

The unique overflow design minimizes splashing and operation noise, making it ideal for sensitive species such as shrimp and betta fish. The bottom pump reduces noise further, creating a tranquil environment.

Fast Start & Adjustable Flow

Simply plug in the filter for immediate use; no water needed. It automatically restarts if the power is interrupted. The adjustable flow knob lets you fine-tune the water flow, making it perfect for feeding times.

Easy Installation & Sizes

Available in two sizes: the 79 GPH filter (5.5” X 3.5” X 2.6”) is suitable for 4-21 gallon aquariums, while the 153 GPH filter (6.9” X 3.7” X 8.7”) is ideal for 20-50 gallon tanks.
