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

So many bad reviews about it being too light, blisters coming from one side etc. All because of one simple mistake, the clip on the back is not part of the decoration but a shipping lock. I also went through frustration within an hour. Then I pulled out the clip and the ornament works exactly as I remembered it as a kid 45 years ago. ps You need a control valve to control airflow at slow speed.
