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 (T100)

Much smaller than normal aerators-also the shape helps too. Nice design & able to be modified to fit smaller spaces.

The diffuser does exactly what the manufacturer says. It emits a huge stream of nano bubbles. I run mine with a Sunsun CT402 air pump. I can have it running on full like in the picture, or dial it down using the supplied valve, which I do when it comes to feeding time. In the carton along with the diffuser was a yellow valve and a metre of air hose, and 2 plastic sucker attachments. The suckers are, to say the least, not quality products, so I replaced them with suckers from my spares box. I purchased this product on the 4th of July. Amazon told me I would receive it by 16 July. I received the diffuser on 10 July. Now seeing as I can order a product from a store in Auckland, and it can take a whole week to get to me in Blenheim, I think the service of the company that supplied the diffuser is second to none. I have had the diffuser running now for 7 days straight without any issues. No mould, as if mould could be a problem in a aquarium, no breaking glass, because we are careful with all thIngs pertaining to our aquarium, no dust or debris coming from the diffuser, just like any other air stone. So, in summary, a quality product that does exactly what the manufacturer says it does. Only let down is the suckers supplied are crap. And the only other problem with the product is the human element, and that is why some of us weren’t allowed to use scissors at kindergarten.

This is my third one. They get clogged and the air flow is diminished after several months

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!

I was super excited for this airstone, and it looks so nice in the tank because it’s so clear and sleek. The crabs and snails love to sit on it. The disappointment that I have is that only half of the stone produces bubbles even after all several days of having it in the tank. This is a disappointment, but when I Messaged the seller via Amazon, they never responded.

Got this to go with a new 1 watt pump for my 3.5 gallon fish tank. This bubble stone is much more quiet than a standard bubble stone or the plastic bubbler I had with colored lights. I like the look and it is supposed to oxygenate the water better. The fish seem happier as the bubbles don't stir up the water hardly at all. Fish are swimming around more instead of hiding from the turbulence. Would reccommend for any other small or Betta tank. :)

Added to my Fluval Flex 15 Gallon and it's working great. The included valve that helps control the bubble flow. Overall, great item, should've added sooner.

Was exactly what I wanted.

Love this. Would highly highly recommend.

Très contente des bulles fines et donc du remous en surface pour aérer. Seulement la pierre dessus est devenue verte en 2 semaines pourtant je n'ai pas d'algues ! Même en brossant la surface impossible à retirer c'est comme tâché et incrusté au plus profond. Le seul moyen serait de faire tremper dans la javel ce qui le rendrait toxique une fois dans l'eau de l'aquarium. Je recommande pour sa beauté mais si vous êtes exigeant sur l'esthétique du bac laissez tombé. Le mien a été retirée après 1 mois

The product works well as described. Nice fine bubbles

Does a good job with aeration, but it does turn black/brown very quickly.

The media could not be loaded.  Great bubbler and works well even if you intend to hide under rocks / gravel.
