How to Clean Air Stones

Air Stone

An air stone is an essential component of many aquariums and hydroponic systems, providing oxygenation for fish and plants. Over time, air stones can become clogged or dirty, reducing their effectiveness. Regular cleaning is necessary to maintain optimal performance and ensure a healthy environment for your aquatic friends.

Here’s a step-by-step guide on how to clean air stones:

  1. Remove the air stone from the aquarium or hydroponic system. This may involve disconnecting tubing or removing it from the airstone housing.
  2. Inspect the air stone for signs of debris or buildup. If you notice any visible dirt or discoloration, it’s time for a thorough cleaning.
  3. Fill a container or bowl with warm water. Avoid using soap or any harsh chemicals, as they can damage the air stone or introduce toxins into the water.
  4. Submerge the air stone in the bowl of warm water. Allow it to soak for 15-20 minutes. This soaking period will help loosen any accumulated dirt or residue.
  5. Gently scrub the air stone with a soft brush or toothbrush. Be careful not to use excessive force, as air stones can be delicate. Focus on the tip and sides of the stone where most clogs occur.
  6. Rinse the air stone thoroughly under running water. Make sure all traces of dirt and cleaning solution are removed.
  7. Before reattaching the air stone to the system, ensure it is completely dry. Allow it to air dry naturally or use a clean cloth to pat it dry gently.
  8. Once dry, reattach the air stone to the aquarium or hydroponic system, ensuring all connections are secure and airtight.


  • Consider cleaning your air stone at least once every two weeks to prevent significant buildup.
  • If the air stone is heavily clogged and soaking doesn’t help, you can try using a weak mixture of hydrogen peroxide and water. Ensure you rinse it thoroughly afterward to remove any remaining solution.
  • Always disconnect or turn off the air pump before cleaning or removing the air stone to avoid potential accidents or damage.

Regularly cleaning your air stone will help maintain optimal oxygenation levels and ensure the longevity of your aquarium or hydroponic system. By following these simple steps and avoiding the use of harsh chemicals, you can keep your air stone performing at its best, providing a healthy and thriving environment for your aquatic buddies.
