Review on 🐠 Optimized Search: uxcell Black Bubble Air Stone Diffuser for Aquarium Fish Tank Pond Pump by Maya Rico

Large air vent with many small bubbles. I was worried that after a few weeks this air stone would clog up like the others and just start making these huge bubbles, but it has been running consistently with very little flow decrease for about a month now. It's a little more than I expected but well worth it. The fit is very good, high quality, it stays in great shape and holds the MT python air tube like a champ.
