Upettools Aquarium Air Stone Fish Tank Nano Bubble Stone Kit with Control Valve Quiet Super-High Dissolved Oxygen Diffuser Makes Super Tiny Bubbles for Fish Tank and Hydroponic (T60)

Easy to install and adjust the amount of bubbles you prefer. Suction cups are strong and stay on the glass.

The media could not be loaded. I stock up on these. They work great. I wish I can get the stone clean after being in the tank for a year. But it's not expensive so I just replace every year.

Really nice air stone, I am able to bury it a bit under the gravel to keep the bubbles at a high output but still not get that splashing at the top of the tank lid.I’ve been using mine for months and still works great. It does turn brown after sometime and it’s not possible to clean the stone part but the design make it easy to bury which is what I wanted. Great for the price, and the noise is what you’d expect from any air stone, that hissing sound.

I have tried several bubble stones, including more expensive ones, and this one is definitely the best. It creates more bubbles than any other stone I have tried, so much so that the bubbles almost create a foam of tiny bubbles on the surface. My black Mollies love to swim through these bubbles.

BEWARE, you need additional parts. Did not make that clear when I bought it.

The media could not be loaded. Came nicely packaged. The stone comes with 2 suction cups and a mount for the stone. I never had this fancy of a bubble stone before. I usually bought ones that you place or try and hide but this one looks classy, very clean. I like how you can suction cup it anywhere in the aquarium. If you want bubbles on the top half of aquarium, attach it halfway up the aquarium. I was used to just buying the stones that lay at the bottom of the aquarium so this was a nice surprise. Really lets you make your aquarium look unique. Came with a yellow regulator valve, so you can control how much or how little bubbles you have in your tank. It’s a fancier valve then i had before, its a good size, easy to twist and even includes a seal inside for leak proof operation. Refer to picture of size difference between the tiny blue regulator valve that i had, compared to the yellow one that came with this bubble stone. The size makes it very easy to turn and adjust. The regulator being included was a nice surprise since i never bought a bubble stone that came with it! This bubbler is nicely made, looks classy not cheap! In the video, you can see what it looks like at the various different levels adjusted by the regulator. Overall i am very happy with this item and it is definitely worth the money! NOTE: you do need to have your own tubing, it did not come with any tubing to connect it to your air pump. Also, i would recommend buying a check valve in addition to this stone. I had a check valve already but if you dont, buy one! You dont want the airpump to fail and all of a sudden your whole aquarium drains through the airstone all over your house!

This stone lasted less than two months (the return period was 30 days). It was great initially. I tried to clean it with hydrogen peroxide but no success.

I have used this diffuser for a few months now and I am very happy with it. It makes a lot of tiny bubbles which get dispersed through the aquarium as a fine mist. The bubbler is very quiet. After a few weeks I noticed the bubbles getting larger so I soaked it in a bleach solution. This cleaned out the pores and the bubbles returned back to being really tiny. I tried to use it for my DYI citric acid/baking soda generator but no gas was released. I will try again soon for I might have made a mistake. I am ordering 2 more for my other aquarium for I think they are worth the money.
