Setup and Installation
- Prepare Air Tubes: Cut the air tube from the middle or any desired position to fit your setup.
- Connect Check Valves: If the pump is placed below the water level, a check valve is required to prevent water backflow into the pump. Connect one end of a cut air tube to the air pump's outlet and the other end to the check valve. Ensure the check valve's arrow points towards the air stone (away from the pump).
- Attach Air Stones: Connect the remaining end of the air tube (from the check valve, if used) to an air stone.
- Positioning: Place the air stones in your aquarium. The pump can be placed on a flat surface or clipped to the side of the tank or a bucket using the integrated metal clip.
