What Kind of Air Stone Should I Use?

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 globular, disc, or even cuboid shape. The cylinder shapes can exist in many sizes and colors. Disc shapes can stay steady at the bottom of your tank, while globular ones can produce more bubbles in the case of the same size.

1.2" Air Stone Cylinder

The tiny cylindrical bubblers are well built for continuous use. They can be easily driven by nano pumps of 2 W - 4 W for constant bubbles.

Steady Medium Bubbles

With constant jetting volume of 1.3 L/min, each bubbler produces numbers of medium bubbles bursting steadily to increase oxygen level.

Easy to Use

Soak the stone in water about 1 hour before use. Clean it regularly as it gets clogged and replace it when not working properly.
