Let’s start it! Firstly, you need an air pump which is suitable for your air stone’s size. You also need flexible airline tubings such as a regular valve and one-way valve. In order to run up the air pump, you have to link one end of the flexible hose to the pump outlet. It will function as a bleed valve when you splice and leave an inch of length in the regular valve. Thus, you can easily handle and adjust the flow rate of the air stone.
Finally, let’s move down to 2 inches of length and splice in the valve. It will prevent the water from backing up into the tube. Continually, air stone is placed into a fish tank which is near an end of the tubing. Place the pump, and make sure that it does not have any contact with water.

If you use skimmer protein to drive air stone, the wooden one creates a chain of smooth bubbles. Therefore, it makes the skimmer protein more effective than ever.

On the other hand, if the airstone functions as decoration normally, any shape comes up to your tastes. There are long or short air stones with mutable lengths, or you can get some round, flat and even rectangular design that you want. Whenever you look for it with only decoration demand, there are many picks for you. Please remember that the larger air stone is; the larger air pump is.
