Review on 🐠 Aquarium Enhancement: Penn-Plax Bubble-Wall Air Diffuser for Optimal Water Oxygenation by Marcia Estrella

OK. That's easy. This is the best bubble wall out there. You can cut them with scissors to get different sizes and you can even connect them. They beautify my aquarium. Bubbles are so cool. No leakage at the connection. The included suction cups are great. I had an unfortunate diatom bloom that affected everything in my tank including the bladder wall. I just threw that wall away and replaced it. But to my shame, I'm stocking up on those bubble walls because I'm afraid they'll stop making them! You will not be disappointed!
