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

These are amazing- they really have bubbles coming out fast!

Work great

Aquarium Stones work great. Quantity is a must.

Airstones are nice overall, and I've had them running outdoors in a birdbath the entire summer without issue. I plan to leave a few bubbling through winter and they might even survive the frost.The only complaint is that each airstone has a slightly different throughput, so if you had planned to hook up more than about 3 to a single air pump you may not like the results. One will put out a ton of air and the rest will barely bubble. You can try to switch them around until you find a set that works well together.

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.

Quality is fantastic they are quite and last a long tinw

Works well kinda loud tho

Great value and has been a Great produce for years:)
