Pawfly Aquarium Air Stone 1 Inch, Fish Tank Air Stone Aerator Bubble Diffuser for Nano Air Pumps Small Buckets and Fish Tanks, 10 Pack

These are excellent, very reliable to change out. They are still more frequently for better flow. There’s no leakage fit with the tubes is perfect and these stones are durable. The air flow through the stones is good noise level as expected installation incredibly easy. I will definitely buy these again.

Hard working. Nice small bubbles for a nano tank. The improvement of the fish was really noticeable.

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.

theyre cheap but do clog somewhat quickly

These work fantastic. And you get so many for a good price,

Bought these to help out with small hydroponics systems. Great air flow, good durability, a bit more noise than the smaller ones but nothing too bad. Compatible with standard fish tank hoses.

Great standard air stone good value for price. Everything was as expected with my purchase except 2 of them did break in the package and all of them did have scuffs and material that had been rubbed off from moving in the package during Shipping. I only needed 3 so the 2 broken ones are fine with me but packaging could be a bit tighter so they don't move and grind against each other and cause damage

These work great.

good

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

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

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.

Work well! Long lasting!!
