8-inch Grey Micro Air Stone Bar

An air stone, whose purpose is to gradually diffuse air into the tank and provide oxygen for fish to breathe, is a necessity to have around your house if you are a lover of aquatic animals.

The 8 inch air stones are made of non-toxic carborundum material. With high temperature sintering, the stones are sturdy and durable, have high dissolved oxygen rate and create even and tiny bubbles rather than a limited number of large ones.

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.
