In my reactor I have half of a kitchen scrubbie. It is open mesh and the bubbles break up really well as they swirl against it. I have also used nylon netting in my reactor, the fine nettting was too tight, and I got some larger mesh, but hae experimented with pond filter pad and now have returned to the scrubbie since the plants are so tall now that the color isn't an issue.
