Updated Version Crazy Air Stone by Pawfly

We updated our high quality air stone into this new crazy one.
We choose this best quality material that will create an abundant tiny bubbles rather than a limited number of larger bubbles.
We change the connector from plastic into stainless steel which is more durable to use for a long time.
Each air stone is 2 inch in diameter. Each Net Weight: 4 oz / 120 g.
Fits for 3/16" / 4 mm inner diameter tube.

Usage:
Please soak the air stones in water for about 6 hours before usage.
After a long-term use, clean your stone regularly so that it will be most effective.
If the air stones just have bubbles in one part, please change a pump of higher power.
