  • Not the best airstones...
Color: 6-Pack
Two of the six air stones worked. Two didn't have any air bubbles when attached to my air pump and two displayed air just out of the top of the stone. I even tried soaking them overnight. But the porosity (or ability for air to pass through) did not improve.
