Description

About Sizes Basically bigger air stones can produce more nice bubbles when connected with 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. So choose a proper air pump according to the size of your air stone. About Shapes The most common shape of this device is cylinder. However, you can also find it in globe, disc or evenly cubic shape. The cylindrical stones exist in many sizes and colors, the disc-shaped stones stay steady at the bottom of your tank and the globular ones can produce more bubbles in the same size. You need an air pump more than 2.5 W to run this stone. Soak the stone completely in water about 1 hour before use. Clean the stones regularly as they get clogged and replace them when not working properly.
