Review on Pawfly 4 Inch Air Stone Disc Bubble Diffuser: Enhance Your Aquarium with Suction Cups! by Mary Hunt

I was skeptical based on some negative reviews but bought it anyway. I installed an air stone disc in my 20 gallon molly/swordtail tank and it is way better than my previous air stone rod. I soaked it in warm water for about half an hour before placing it in my tank so all the "air holes" were filled and ready to go. It works fabulous. Lots of bubbles even if covered in gravel. I had a bit of a hard time connecting the air hose, but when I did it fit snugly and snugly with a bit of wobble. Good price! I would also recommend it to other crafters 👍Ps: I uploaded a video so you can see it in action. My tank needs a water change and I usually use a toothbrush to brush the algae/dirt off my airstone to keep it from clogging. Usually there are more bubbles than in the video, but I decided for now that there should be 😁 enjoy!
