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

At first this seemed to work fine. There were a lot of air bubbles, they were nice and small which allowed them to circulate around the aquarium quite well. I once left it unplugged overnight to plug in something else and the next day when I plugged it back in it stopped working. I took it out and rubbed it as best I could but there were no blisters. So I took a needle and made about 10-15 small holes and now the bubbles come out very big and destroy the reservoir. The build quality is very exceptional and the price is spot on. But it took less than 12 hours after turning it off before the pores became clogged and stopped working.
