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

Great quality. Make good bubbles for my Axolotl. I like that it comes with the splits. The pressure is awesome not overly strong. Great price I will definitely buy thses again!

Works great

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.

I'd question using >1 on a single air line with others following the 1st. The 1st looks and works great even as the stone is getting dirty. The 2nd was always never equal to 1st and at least 50% less bubbles. And now it's dirty no bubbles at all. Maybe a stronger air pump is needed. But disappointing I can't enjoy more than one.

They're amazing!!! My last airstones lasted nearly 2 years before they needed replacing. I highly recommend these air stones.

Loved these! They worked exactly as they were suppose to and are pretty big compared to the normal size air stone I normally use for the aquarium! I would recommend/repurchase this again!

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

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.
