Attach this air stone to any standard 3/16 airline tubing (sold separately) and its ready to use. For larger tanks, multiple air stones can be used in a series. Position this air stone flat or at an angle; its blue colour will blend in with the surroundings of the tank.
The air stone can also be covered in gravel to be completely hidden from sight. The extended sides provide leverage to prevent the air stone from floating in the tank and can be secured under gravel. This aquarium aerator measures 25cm by 5.1cm and is suitable for both freshwater and marine tanks.
Long lasting and durable, the Penn Plax Aquarium Air Stone is a smart choice for any fish enthusiast.
