About this product
The pack holds 10 of these aquarium air stone balls, each 0.8 inch in diameter and 0.7 inch high. Pawfly made them from mineral material sintered at high temperature, and they are meant for small fish tanks or aquariums. The pair of numbers that decides the setup is the tubing: each ball takes standard airline tubing with a 3/16 inch inside diameter.
Air pump power and airflow
A pump rated between 2 W and 4 W is what the manufacturer recommends for one of these stones. At that power the stone passes a jetting volume of 1 L/min. Each ball weighs 0.3 oz, and the manufacturer describes the build as made for continual bubbling.

What the ball shape and sintered material give you
- The ball measures 0.8 inch across and 0.7 inch high, so it sits low in a small tank.
- Sintered mineral is the material, which means the stone is a porous body rather than a perforated plastic shell.
- Pawfly rates the output as a good amount of dense bubbles.
- The stone is built for continual bubbling rather than occasional use.
- Standard 3/16 inch ID airline tubing pushes onto the stone.
- At 0.3 oz per ball, ten of them weigh little together.
Soaking and cleaning the stones
Before the first use, the manufacturer says to soak the stone completely in water for one hour. After that, clean it with a brush once it starts to clog; Pawfly notes this happens after weeks or months of use.
Will this air stone suit your tank?
Check the tank first: the manufacturer names small fish tanks and aquariums as the setting for these stones, so a large tank is outside that description. Check the pump as well, because the recommendation is 2 W to 4 W, and match the tubing to a 3/16 inch inside diameter. Each stone is 0.8 inch in diameter and 0.7 inch high, which is the space it takes up in the tank.
