Review on 🐠 Pawfly Small Air Stone Diffuser for Aquarium Fish Tank with Pump - Bubbler Airstone by Joe Mendez

I bought these to replace old stones in my freshwater aquarium. I use an air pump rated for a 100 gallon tank, even though my tank is only 30 gallons. Yours worked fine for about 2 days and then stopped releasing air. I swapped out both air stones and they didn't work at all. Unfortunately, I thought my air pump had failed. I ordered a new one and it worked great with the new bar style air stone. But these still didn't work. I ended up throwing them all away and buying slightly more expensive stones.
