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.

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.

I ordered 4 of these, opened two, soaked them as needed, then tried them and got not 1 bubble from either, and I am using a 39w commercial pump, even tried the bigger pump I have, 109w or so, and nothing.. I have many other little air stones that work, but these are not functional at all, and a waste of money, hopefully I can return them at no cost to me, because they do not work at all.

Trust the negative reviews. It's not you or your pump, these truly don't work. Chewy was of course supportive as ever and refunded me.
Stronger air pump needed, but works great.]pp

I bought two of these to make a air curtain along the back of my 20 gallon tank. It didn't work so well at first until I realized I needed a stronger air pump. Now I'm using a Tetra Whisper 30-60 instead of the 10-30 and it's working great, I'm getting a full curtain of air. I'm about to do the same with my 55 gallon tank so I think I'll need at least a Wisper 150 to get the same effect with 4 or 5 of these Add-A-Stones.

I bought a 10 inch stone. I only get 3 inches of bubbles coming out of the air stone.
Nice long air stone
