Setup Instructions
Follow these steps to set up your Pawfly Air Stone Disc:
- Prepare the Air Stone: Before placing the air stone in your tank, soak it in water for at least one hour. This helps ensure optimal bubble production.
- Connect Air Tubing: Attach one end of the provided 60-inch air tubing to the inlet nozzle on the air stone disc. The other end of the tubing will connect to an air pump (air pump not included).
- Position the Air Stone: Place the air stone disc at the desired location in your aquarium. Use the three firm suction cups on the bottom of the disc to secure it to the tank floor.
- Connect to Air Pump: Connect the free end of the air tubing to your aquarium air pump. Ensure the connection is secure.
- Connect Power: Plug the UL certified power adapter into the air stone disc's power input. Then, plug the power adapter into a suitable electrical outlet.
- Cable Management: Use the additional suction cup to fix and organize any long or messy power cords, keeping them tidy and out of the way.

Operating Instructions
Once properly set up, the Pawfly Air Stone Disc will begin to operate automatically:
- Bubbler Function: When connected to an air pump, the 2-inch disc will produce a steady stream of fine, micro bubbles. These bubbles increase the surface area for gas exchange, promoting oxygen supply in the water, which is beneficial for aquatic life.
- Multicolored LED Light: The integrated LED lights will emit 6 different colors. These colors change slowly and alternately, creating a dynamic and visually appealing effect in your aquarium.
- Low Output Voltage: The device operates at a low working voltage of DC 12V. This ensures that the light and electrical components do not negatively affect the health or normal life of your fish.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your air stone disc:
- Cleaning the Air Stone: Over time, the air stone may accumulate dirt or algae, which can reduce bubble production. Periodically remove the air stone from the tank, disconnect the air tubing, and gently clean the surface with a soft brush or cloth. Rinse thoroughly before re-installing.
- Power Cord Inspection: Regularly check the power cord and adapter for any signs of damage, fraying, or wear. Replace immediately if damage is found.
- Suction Cup Check: Ensure the suction cups remain firmly attached to the tank surface. If they lose suction, clean them and the tank surface thoroughly before re-attaching.
