What Kind of Airstone Should I Use?

Let’s clarify basic knowledge:

A bigger air stone needs a more powerful pump to produce more bubbles.

Basically bigger air stones can produce more nice bubbles and they're used for powerful air pumps.

If you connect a bigger air stone to a small pump, the bubbles will be produced only at the front of the stone.

Small pumps go well with small air stones while powerful pumps and small stones don’t get along well.

About Shapes

The most common shape of this device is cylinder, however you can also find it in globe, disc, or even cube shape. The cylinder shapes can exist in many sizes and colors. Disc shapes can stay steady at the bottom of your tank, while globe ones can produce more bubbles in the same size.

You need an air pump more than 2 W to run this stone.


Soak the stone completely in water about 1 hour before use.


Clean regularly by a brush as they get clogged after weeks or months of usage.
Replace the stone after it stops working properly.
