This air stone is pretty good. The thing is the bubbles come out near the airline. Its still okay though.

Rated 3 out of 5 by Barb12 It's okay
I got this particular air stone about a year ago. It doesn't really act how an airstone should because the bubbles come out near where the airline connects to it not being diffused as I have seen other airstones.
