Noticed clearer water and healthier fish since using them. Highly recommended!

These appear to be porous ceramic balls but they do not permeate water at all. If you buy higher quality balls, you can put one up to your mouth and basically blow right through it because the internal pore structure is connected. These balls are "closed cell" and do not allow for any air/fluid to pass through the balls.
