Round Golf Ball Air Stones are made from compressed mineral sand. They produce fine to medium sized air bubbles when connected to an air pump and help to maximise the oxygen levels in your aquarium, fish tank, pond or reservoir by moving water to the surface.

The air stones supplied may vary from grey to blue. 

Air Stone Sizes and Options Available

  • 50mm in diameter
  • Quantities of single, 2, 4, 10 or 24 air stones

Note: These air stones may come with minor surface imperfections from shipping.


Good air stones are vital when the weather gets warmer

  • As air stones age, the bubbles produced get larger which makes the surface area of the air produced actually go down!
  • Less surface area means the effectiveness of the bubbles goes down, less oxygen into the water.
  • Combined with this, as the water heats up in summer, less oxygen is available in the water due to the temperature.
  • Fresh, new air stones, produce the finest air bubbles which makes the oxygen transfer the best it possibly can be.
