Pawfly Aquarium Air Stone Disc for Air Pump 5 Inch Fish Tank Air Stone Bubbler Bubble Release Tool Oxygen Diffuser for Fish Tanks Buckets Small Ponds and DWC Systems

This works great. The rubber feet attached the air stone to the wall just fine. The bubbles are fine and consistently flowing. I don't know what size tubing I used but I had two sizes and this needed the larger one. So confirm what size air tubing you need. Air tubing is not included with this air stone.

Just what I wanted for a project with hydro plants with super fine bubbles-sleek design-good value

I have a 10 gallon tank filled with gold fish which are notorious for being dirty fish. The air stone collects algae more than anything else in the tank, it’s difficult to clean due to how porous it is. Not the fault of the manufacturer, could just be my setup. Stone works well and puts out a lot of bubbles. The fish seems to love it.

I ordered four of the 4” rounds for my 75gal. They are great and work as stated and no issues with the actual air stone.However, moving the gravel out of the way and placing airs stones on the glass bottom was more of challenge than expected; the suction cups don’t stay in place all that well and if there’s one piece of gravel underneath the surface of the air stone the suction cups won’t stick in place, because they’re too short…was fun to put 4 in their places (eye roll).All in all I’ll probably by again and deal with the install…as I like how they work and the round looks nicer than the long rectangle.FYI soaked them for an hour prior to installing and I do believe this helped!

The media could not be loaded.  As time passed (3-4 months) the bubbles became less fine, but that doesn't bother me at all (there's still a a possibility that the bubbles look "thicker" because the stone is covered with rubble)Pros:- large size, which creates a nice round column of air in the middle of the tank- has never come off from the bottom of the tank, once I secured it with the suction cups- can be nicely buried under the rubble- this is a fraction of the price you usually find for any accessories in the pet storesCons:- none so far

For a fairly expensive air stone, I’m not impressed. I hooked it up as a single item to my heavy duty pump and only part of the pad lets bubbles out. I worked with it for over an hour, trying to get it to emit more bubbles. Nope. Very disappointed.

Nice heavy base that sinks to the bottom, 3/8 port piped to a VIVOSUN air pump works perfect! It stays put and provides plenty of air! Ready to buy a 2nd!

I was not able to use it before the 30 day return policy and unlike the product video that shows the full stone giving bubbles only the very middle is working but had to use it and most of my shrimp died $40 worth. I would not buy again.

Llevo una semana usándolo y todo bien hasta ahora.
