3. Connect the air tubing to the pump’s outlet, distribute the air stone evenly in the aquarium, and turn on the power. The pump will begin to draw in air and provide oxygen.
4. Choose between single or double air outlets depending on your oxygenation needs.
5. Clean and replace the filtration cotton and air stone every three months for optimal performance.
6. When not in use, disconnect the pump from the power source and store it in a dry place.
