With Penn-Plax Add-A-Stone Air Pump Accessories, you can create a stunning flow of bubbles while increasing the aeration in your aquarium. It uses a standard 3/16” connection to attach to tubing and air pumps for a steady stream of bubbles. You can connect additional air stones or ornaments to the other end, which is much more efficient than running tubing from each accessory. The Add-A-Stone can be set at any angle in the tank or even buried without the fear of clogging.

A second connection allows for the addition of more air stones or ornaments so there is no need to run an additional lines all the way back to your valves or pumps
I could only get the bubbles to come though half of the bar. For context, I had a pump rated for 100gal tanks used for a 36gal tank. So I feel like it should have had enough power to push them all the way through. Even when I connected tubes to both ends with 2 air pumps, only half of the bar worked.

Bought 2 and opened one but it wouldn’t produce bubbles. Haven’t tried the other because I don’t want to waste my time.
Use 2 airlines

If you run an airline to both ends it work great. I started with one airline and only half the stone was making bubbles.
Works a little too well in my tank

I have a 5 gal tank. Based on reviews I didn't know if this would pull off or not but it actually looks pretty good

Wide range of fine bubble. Ive placed it under a piece of coral and it looks as natural as can be.
should have read the reviews first

I bought this as a replacement for an air bar that was nearing the end of its life, however this didn't put out any bubbles, nothing. I tried using a different pump for bigger tanks but still didn't get anything. Should have read the reviews first. It would have been an awesome addition to my tank if it worked.
Not worth it

The 10" bar only puts out bubbles from a small section closest to the connection to the air hose. I've tried it with 3 different pumps and no change in results. Don't waste your money.
