Review on 🐠 Quickun Aquarium Oxygen Diffuser Bar: Enhanced Air Stone Bubble Wall Tube for Fish Tank Décor - Available in 7'', 10'', 14'', 18'', 23'', and 28'' Lengths by Amanda Schnurr

When I received the product it had instructions on how to drill some holes in it to improve airflow I think? But I didn't when I put the bubbler in the tank and it worked so well! (See below photo) it worked really well for a few days, I cleaned it up, put some light gravel on it and it worked! It was wonderful. I had a bit of an issue with it staying in the suction cup holder, it snapped into place but popped out easily and didn't stick very well. I woke up one morning and it suddenly stopped. I flushed it, used different hoses, air pump, air connector, etc. Nothing worked and I had to return it. I tried punching a few holes in it as directed but that didn't help either. The product is cheap, I will surely buy something better.
