The Aquarium Co-Op Weighted Air Stone diffuses air from an aquarium pump into bubbles that agitate the water surface and support gas exchange. Its weighted design helps it stay submerged without a separate anchor.
Features
Modular design: Plastic disc sections can be added or removed to adjust air stone height
Weighted: Designed to sink and stay positioned underwater
Compact diameter: Can fit inside many compatible air-driven sponge filters
Easy maintenance: Detachable sections help with cleaning
How to Use
Connect the air stone to aquarium airline tubing and a suitable air pump. To adjust its height, grasp the bottom firmly and pull the modular sections apart; add or remove discs and press together securely. Verify clearance inside your sponge filter if using the air stone internally. Aeration effectiveness depends on the pump, air flow, and aquarium conditions.

Setup Tip
Connect to suitable aquarium airline tubing and an air pump. A weighted air stone remains submerged but still requires air supply. Use a check valve when needed to prevent back-siphoning toward an air pump placed below the waterline.
