Setup Instructions

  1. Soak the Bubble Disk: Before initial use, soak the bubbling stone disk in water for at least 1 hour. This helps to ensure even bubble distribution.

  5. Position in Aquarium: Place the bubbling stone disk at the desired location on the bottom of your aquarium. The integrated suction cups can be used to secure it in place.
  6. Connect Power Adapter: Connect the power adapter to the LED bubbling stone disk. Ensure the connection is secure.
  7. Create Drip Loop: When connecting the power adapter to an electrical outlet, create a "drip loop" with the power cord. This prevents water from traveling along the cord and reaching the electrical outlet, ensuring safety.

Operating Instructions

Once properly set up, the NICREW Multi-Colored LED Aquarium Bubbling Stone Disk operates automatically:

  • LED Lights: The built-in LED lights will automatically cycle through multiple colors, creating a dynamic and visually appealing effect in your aquarium. This effect is most pronounced in a darkened room.
  • NICREW LED Bubbling Stone Disk creating colorful bubbles in an aquarium

  • Bubbling Function: When connected to an air pump, the disk will produce a continuous stream of fine bubbles. This promotes water circulation and aids in oxygenation within the aquarium.

Maintenance

Regular maintenance ensures optimal performance and longevity of your bubbling stone disk:

  • Cleaning the Stone Plate: Over time, algae or mineral buildup may reduce the airflow and bubbling efficiency. If this occurs, disconnect the device from power and remove it from the aquarium. Use a stiff brush to gently clean the surface of the stone plate.

  • Air Tube Inspection: Periodically check the air tube for kinks, blockages, or damage. Replace if necessary to maintain consistent airflow.
  • Power Cord Inspection: Regularly inspect the power cord and adapter for any signs of damage. Do not use if damaged.
