Customers like the size of the air stone. They mention it's really large, perfect for a US 5 gal water jug, and has a large surface area for air distribution. Some say it'll fit in a 20 gallon aquarium.

Customers are mixed about the bubbles. Some mention that it makes lots of bubbles, keeping the water moving. They say it's especially useful to bubble standing water to keep it fresh and clean. However, some customers say that it only produces large bubbles from the top, and the air bubbling is reduced significantly with sludge or algae.

"I use this to keep my minnows alive here. It has enough bubbles to keep the water moving even when it’s really cold and it keeps it from freezing..." Read more

"...Makes a lot of bubbles. Should look better with a bigger pump. Using it to aerate my saltwater and also my hydro sump." Read more

"I use these stones to bubble organic compost tea. Plenty of air flow and no issue with clogging up. Nice air stones." Read more

"As others have stated, air does not go through the stone, just a few bubbles coming out at the top by the hose. Better aeration without the stone...." Read more

"...to get the airstone to the bottom of the pond, tank, etc... Airflow was excellent and I'm glad I bought these." Read more

"Great for DWC gardening. Produces enough air flow to keep my plants happy and alive." Read more

Customers are not happy with the leakage of the pet supplies. They mention that it leaks around the air tubing nozzle, from the seal, and around the plastic connection. They also say that it is not properly sealed at all.

"Delivers lots of bubbles of adequate size. Sometimes leaks a bit around the plastic connection to the stone, but a bit of epoxy fixes that up...." Read more

So I have one of these on each line out of a Tetra 100 gal pump. I have them in a 4 gallon DWC I put together for the kitchen. Fantastic output and should have strawberries in no time! Previously I had 4" disk types that were okay, but these really put out the bubbles!

5.0 out of 5 stars Creates good aeration bubbles in our pond
Reviewed in the United States on November 7, 2019
Verified Purchase
We have a small 400 gallon fish pond in our back yard and I use these stones to help create aeration bubbles to help obscure the view of the in-pond filtration device. The fish love to swim through the bubbles, too.
In the winter, I pull these stones up to the higher level and they work wonderfully to create enough air movement in water to keep all of my fish alive and keep two openings in the ice. I would recommend using these over purchasing a $100+ pond heater. This has worked for us for several years.
These stones were heave and sturdy. We are pleased with the stones.

3 of the 4 I bought worked beautifully; the fourth, I had to reseal - the air blew right out at the connection, instead of through the stone. Overall, these air stones are large, but not as effective as others I've had. I bought them to use in Koi pond moving bed bio-filters, and they will suit that purpose well.

5.0 out of 5 stars Perfect Product - Great Value for Two Pieces - Ensure Your Pump is Strong Enough
Reviewed in Canada on May 21, 2019
Verified Purchase
I've tried the VIVOSUN, Pawfly, ActiveAir, and an assortment of smaller variations (I learned after a while to stick with the 'pop can' versions for DWC Hydroponics). The VIVOSUN stones seem to distribute the smallest, finest bubbles over the greatest area. I commonly use one stone per bucket, but I recently ordered more and added two per bucket. Growth has exploded. I didn't really expect it would make much of a difference and I just wanted to make use of an extra air pump I had, but the results are undeniable. So, in short, order a few extra and double down. At this price you can't go wrong.

Noob note - never wash with soap and the put stone in reservoir. You will be giving your plants a bubble bath. Soak stones in ph water before use.
