The 30cm airstone works well with my air pump and creates a steady bubble flow. My fish seem more active and the water looks clearer. It fits nicely in the tank and doesn’t block the view.

I’ve used this for a few months now and it’s still performing well. The bubbles are fine and don’t stress my fish. It’s a good size for my 120-liter tank.
Vanessa Ferguson –
The bubbles are consistent and the stone looks great in the tank. My betta fish swims around the bubbles and seems more engaged. Easy to install with the included tubing.
