1.6 Inch Air Stone, Aquarium Air Stone, Air Stone for Fish Tank and Hydroponics Air Pump

These air stones produce a good amount of fine air bubbles without a lot of turbulence. They are also heavy enough to stay on the bottom. I have had smaller air stones that needed extra weight like a lead band wrapped on the hose to keep the down.

Item is as described. Thanks

I like how they lay flat as I bury them in the substrate. Nice little bubbles

Diffuses air and makes bubbles as it should.

Works great

good product

Leaks like a siv where the nipple is glued to the stone. was not in a padded package so likely broke in shipping but not sure what i expected for 6 bucks. it works i guess but definitely not creating small bubble like in the photos due to the air leaks on all 4 stones in all the same spots.

Probably the best airstones I've purchased 👌 🙌 Great price also definitely reccomend
