Air Stone Ball (5cm)

The Air Stone Ball 5cm is the standard way to improve oxygenation and water circulation in your aquarium or pond because it is simple and reliable. These are the exact airstones we use and recommend in store, chosen for their sturdy construction and consistent airflow performance across a wide range of tank and pond setups.

Connect to any standard air pump to produce a steady stream of fine bubbles that oxygenate the water and keep it circulating, creating a healthier environment for fish, shrimp, and other aquatic life. The compact 5cm size makes it easy to position discreetly in most tanks.
