How much oxygen do they produce, i know finer bubbles are better that larger ones, but do they really add that much oxygen?

im thinking of putting in my ehiem one with the supplied air stone.

Hi sjolliff

The bubbles themselves don't add much oxygen to the water but they do agitate the surface. This is what increases the oxygen content in the water.

They do look nice and if you have the kinds of fish that like the increased water movement, they are good additions.
