in, use a secure sealing method for preventing the air from leaking. Some airstones may have to be soaked for up to thirty minutes before they can be attached to the tubing. Then place the bubbler stone at the desired position in the tank. Most airstones are heavy and will settle down on the bed of the aquarium. A few of them, especially tube-shaped ones, may come with suction cups for installation. Place the airstone at such a position so that it improves the aesthetics of the tank without obstructing the view. If your airstone has wires for LED lights, then connect the same as well.
After all the connections have been made, switch on the air pump and adjust the airflow using the regular valve as desired. Your aquarium bubbler setup is now complete!
