Key Features

I use these for DWC in 5 gallon ( or 3.5G) buckets - I put the air line into the bucket, and have a tee with each side is going to one of these 3" air stones - for a total of two of these 3" stones in each bucket, and they are great, lots of air bubbles. I use 2 for more air, but also to balance the water motion in the bucket - I have found using just one can cause a circular motion of the water thereby twisting the roots, making less air roots.I tried 4" but thats too big and are prone to sitting sideways or kinking the line.2"are too small and end up "glugging" as the few bubbles collect into bigger bubblesI have bought many of these and will continue.

I grabbed these airstones at a great price, and while they’re smaller than I initially expected, they’re incredibly simple to set up. So easy, a caveman could use them! The build quality ain't the highest (I’d call it mid-to-low), but they’ve been surprisingly durable: after three months of constant use, there have been no leaks or major issues. The bubbling noise is noticeable but definitely quieter than running without airstones. Overall, for the price, they work exactly as advertised, and I’m happy to give them a solid four-star rating.

These bubblers allow me the fun of putting them in the gravel wherever I want. I bury them near the plants and in front of my features. Adds enjoyment to having my aquarium.

I put these in all of my aquariums. They bubble like crazy! I highly recommend them.

The picture only shows the larger 4 inch size which seems to have at least a two-tiered barbed connection. I bought the four smaller ones assuming that it would be the same connection but it’s not. It’s not barbed at all and was bigger than my hose. I had to spend a lot of time soaking my hose in hot water, cutting a slit in it, and putting on clamps to keep it the hose on. A lot of work for what could have been much more simple if there was a barbed connection. I would not recommend the smaller ones to anyone who values their time.

My filter pump stopped working so I purchased this product. I use one stone in my 3 gallon beta tank. It keeps my tank clean twice as long as the filter did. Why? You ask. I have no idea... maybe the water moves more. One more plus, my beta loves the bubbles. He wasn't sure at first. But now he races through them. 😆• It's my opinion this product is a GREAT value for the $.• FYI. This product has no suction ability. Is is designed for an air pump to push air through a connected hose and through the holes in the "air stone".
