These work very well

These work great. I get 10 million bubbles in my buckets. More oxygen for the plants. Very cool. Not much noise and I didn’t detect any odors. Read more

Worry free

These are best. They put out great micro bubbles but most important to me: even full of air they sink to the bottom and stay there Read more

Good product, lousy shipping/packaging
George Reynolds—July 29, 2025✓ Verified purchase
These are tough airstones. I am amazed that they still work at all after the beating they took in shipping. Bashed so hard, they were knocked free of the factory cardboard packaging. Some chips were knocked loose. Amazon put these heavy, brittle stones in an oversized, non-padded plain manila envelope. That's no way to treat airstones. Isn't Amazon supposed to be in the shipping business? Fail. Read more

Exactly what I needed, well-constructed and very satisfied
Kara Wilson—December 29, 2025✓ Verified purchase
Bought 3 of these and using them in 5-gallon buckets with a 20w commercial air pump. They work exactly as expected and well-constructed (the barb and the glue that holds the barb adapter to the stone). Very satisfied with the product. Read more
