Pawfly 1 Inch Air Stone 10 Pieces Cylinder Bubble Diffuser Airstones for Aquarium Fish Tank Pump and Hydroponics Grey/Blue, 0.8 Liters_Per_Minute

Excellent aeration and the stones are excellent in creating the bubbles. Definitely recommended.

The quality is super and does its job. The stone is thin which takes less space, but powerful.

Quality is not upto mark

Crudely made and just about does the work intended. Bubbles or aeration is on larger bubble side with a lot of air leaking at the joint. Good if you are looking for just an air stone and if quality of construct and air bubbles are comprisable.

good

I ordered ash colour stone . But colour stones delivered. Also instead of 10 stones only 9 stones came.

Quality is good and value for money. You don't need to buy again for atleast 1 year since they last long

Good product work properly. Rate is genuine. I'm happy

Worked great and as needed, get nice quantity for low cost

Works as needed- nice to see good air bubble flow coming from the air stones- so much nicer than my ancient decrepit ones Please note these air stones are small and you may want some a bit longer - but still happy with them

hard to find these now days, they work great. easy to replace the old ones. seem to have enough air flow.

I use these inside my sponge filters. They work great. Nice bubbles. I am happy with them. They came quickly too.

They are easy to install onto air hoses. Add a valve inline and they can produce many tiny bubbles up to large ones by adjusting the valve. Once the hose has been installed on it for months, you may not get it off the hose again. These are inexpensive and solve a variety of aquarium situations. I always have at least one bubbling in every aquarium I own. Over months of time, the rock parts will more and more disintegrate. Sometimes they will allow less and less air flow over time till they block off the air entirely. When they clog, there is no fix action. Just throw the old one away and replace it. Generally, most even basic air pumps will be able to run 2 or more of these airstones at once. These are of average to good quality and will generally last several months, constantly bubbling. Good product.
