Review on 🐠 Penn-Plax Air Action Aerating Ornament and Aquarium Decor with Air Bubbler Movement Enhancements by Rhonda Johnson

I previously gave this diver a good rating but over time it turned out to be a disappointment. The first lost all air bubbles from the right ear (they come from both ears). We thought it was a one-time use and bought another. Initially (like the first day) he was in full swing with big blisters coming out of both ears. Now 2 weeks later the right ear is almost dead again and the left ear has shrunk. Thus, the entire block produces practically nothing. This is a poorly made product that clogs easily. Do not worry.
