Quickun Aquarium Air Stone Bubble Wall Tube Oxygen Diffuser Bar Decor Accessory for Fish Tank 18 Inch Length,1PCS

you'll get a fine mist of bubbles and it's perfect for 20lb or less and doesn't require a powerful pump. the suction cups are welcome and help you set it exactly where you want. this is no bigger than a pencil in diameter and length.

Really like these. They are a small diameter and seem to be holding up fantastic. The first month I had them placed just above the aquarium substrate on the back wall of the aquarium. For the last month they have been just under the substrate and are much more quiet. Like you can not hear the bubbles at all. The aquarium friends seem to like them better just buried under the surface of the substrate as well and play in the bubbles.

not the best quality product in the aquatic world but for the price it works, take a bit to get it set up and to stay still but once up and running its great

Product doesn't work. Followed soaking instructions punctured holes, tried single tube and double tube. Tried vertical and horizontal. Used small pump and large one. Bubbles only come out from top cap tube interface.

I bought this one to replace my other one because they do overtime degrade and you have to replace them. But we liked the bright kind of green color originally I had problems getting it to stay on the side of my aquarium. But I think you have to make sure your aquarium is really clean for the suction cups to hold and once I re-cleaned my glass it seems to have stayed where I put it, I feel like for the cost I spent I got good value for my money .

The media could not be loaded. Set it up with air pump 100 gallons for my 125 tank. It really pops up definitely love it

The media could not be loaded. Very easy to assemble and my fishes love it

Maybe my bubbler isnt strong enough? But it's only been a month or so since I bought this and it barely bubbles. So really not worth buying.

These are made of paper and aren't actually air stones.Once I opened the package and realized this I just threw them away.Don't waste your money.Invest in actual, real air stones.
