Hello,
I am looking for the airstone for diffusing CO2 in my tank by inserting it into the tube of the canister filter. Can somebody tell me the stone having a narrow diameter (less than 3/8 inch) and making the finest air coming out please? I could not find such a stone in any local stores. Thank you for your time in advance!!

You may want to try using a "bubble wall". They are relatively inexpensive, and can be cut to any size you would want. They are similar to a straw but made out of a porous material that diffuses the bubbles. You would insert aquarium tubing into one side, cut the piece to the desired length, and then put a cap on the other side...
...but it does take a long time for CO2 to absorb into the water...it requires maximum contact...you may want to consider a diffuser designed for this purpose
