Review on 🐠 Feelers 2x2.75 Crazy Air Stone Bubble Cylinder - Pack of 5 for Fish Tanks, Aquariums, and Hydroponic Growing Systems by Krystle Garcia

Revainrating 3 out of 5

Not standard for aquarium sized air hoses.

I've never seen an aquarium airline with port sizes on these airstones. I probably should have read the size more carefully. I was able to find an air pump hose to try them on and it wasn't great. The bubbles that came out were large and few in number. Not small and tiny like other air stones I've used. I have larger ones in my pond from another manufacturer that have a standard size connector and produce a sea of tiny air bubbles to properly aerate the water.

Pros
  • The round surface and flat bottom make the stone court stable. Low oxygen consumption and high melting rate.
Cons
  • Lots of stuff
