How does it work? I have it hooked to my air pump but only a couple of tiny bubbles on the one end come out.
Answer by ChewyMar 24, 2020
An air stone usually has one port that attaches to an air tube in order to provide oxygen inside a tank. This product has 2 ports on opposite sides of the frame. An air tube attaches to one, and the other is to link multiple stones together. This way, only one air pump is needed, and with only one air tube.

Do I need to purchase an air pump to use this?
Answer by ChewyMar 13, 2019
This add-a-stone accessory does require separate purchase of tubing and air pump to connect to.

How to Solve the Bubble Shortage

I have purchased this item many times and it always has a bubble shortage. It does not distribute the bubbles evenly and or it's a sad little trickle of bubbles that come out. However, I Found a Solution... HOW TO CREATE MORE BUBBLE's: Lightly scratch the surface of the dark blue stone. (I use my fingernails or the back scrubber of an old sponge). Start off lightly as to not create huge gaps or holes in the stone. You may need to test it a couple of times in a small bowl until you have reached your desired amount of bubbles. (Lightly scratching it creates openings in the stone allowing bubbles to come through). Also, make sure the cap on the other end of the stone is Extra Tight. For some reason, it has a loose fit and air escapes out of the end creating a loss in all pressure in order to produce bubbles in the rest of the stone. It is an inexpensive stone that is why I take the time to get it working properly. I also like the length of the item. Other stones are round or small. Hope this helps

Doesn’t fully work

Unfortunately bubbles only came out of the first 1/3 of the bar. The bubbles are nice and big and I guess for the price I paid I’ll wind up keeping it, but I’m disappointed.

Half works

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.

No bubbles

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
