Rise Torrent 2 Inch Nano Air Stone with Case - Silent High Oxygen Bubbler for Aquariums, Fish Tanks & Hydroponic Systems, Black Small Bubble Diffuser Accessories (No Air Pump and Air Tube)

Best air stone I have ever purchased. Betta Loves playing in ithe bubble's. So awesome to watch.

This air stone works great. Used it to replace the stone in my bait bucket.

This air stone produces tiny nano bubbles, but only one of my air pumps was able to force air into it when it was positioned at the bottom of the aquarium. It seems to require more pressure than a simple air store. Also, it forced the air tubing off twice, so possibly some superglue is required to hold it in place before putting it in the tank. I am sure it is more effective in oxygenating the aquarium due to the quantity of bubbles and large surface area of this air stone, but not all people will have a pump powerful enough to drive a through it particularly if they have a deep aquarium.

Definitely not nano bubbles but product is perfectly fine for the price and is quality and very heavy duty

This thing barely puts out bubbles even with the air supply turned all the way up. I Dont recommend

My brilliant fish simply love this .they swim into a circle after breakfast and slowly take turns getting over the bubbles and twisting into various positions and it seems to feel lovely over their scales. They are all much happier . It was very easy to install. It took a couple of days for the fish to decide that they liked it. But now it is a whole new activity option.

My Axolotl loves his bubbler he doesn’t go in and out of it all the time. But from time to time he does. Sometimes lays in it until he goes up then he’ll swim away. Definitely recommend this item. It has been working since the first day and that was about 5 months ago.
