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

Although this stone was connected to a 16LPH air pump, this stone only bubbled just past the plastic end near the inlet. It was also leaking in the intake area. Since the "body" is plastic, I didn't try to tighten the mount. Heavily disappointed.

Have been using these rocks for a while and still happy. There are no leaks and the plastic bumpers prevent damaging the rock in the tank (my tanks have a concrete bottom). The ONLY downside (and a small one) is that the buoyancy of the tube tends to leave those rocks on edge. A bit more weight would be a plus, but not such a big issue that I would stop buying them. A good product.

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.
