5.0 out of 5 stars Crazy Air Stone Bubble Cylinder
Reviewed in the United States on March 26, 2024
Size: 2" x 2.75"-CylinderVerified Purchase
Shipping was quick, these air stones have a 1/4" I.D. inlet thus they do not restrict air flow as most air stones. This also prevents back pressure on the pump itself allowing it to run cooler. Very happy with my purchase.

These are working great in our tank. We need a bigger pump to work them all, but we are currently only using 2 in the tank at this time.

3.0 out of 5 stars Not standard for aquarium sized airline tubing.
Reviewed in the United States on August 26, 2021
Size: 2" x 2.75"-CylinderVerified Purchase
I've never seen airlines for aquariums with the size of connectors on these airstones. I should have probably read the size more closely. I was able to finagle an hose from an airpump to try these out and it wasn't exactly that great. The bubbles that came out were large and few. Not small and tiny like other air stones I've used. I have large ones in my pond from another manufacturer that have the standard connector size and produce a sea of tiny air bubbles to properly aerate the water.
