UPETTOOLS Aquarium Air Stone Fish Tank Bubbler Small Nano Air Bubble Stone Super-High Dissolved Oxygen Diffuser Makes Super Tiny Bubbles 3.2 Inch Airstones

Sits right on the bottom of tank. Only thing I didn’t like was the fact that it didn’t have a way to connect to the plastic piping. I had to use gorilla tape to connect them, but works great now!!!!

I read on the best ways to use this air stone, so I left it soaking in clean conditioned water for the entire night before using it. It gives a huge amount of bubbles enough to make it look like it is not working. It is also quieter than the regular air stone. I am using this for plant cuttings so time will tell. There is no instructions, just the puck which is a great size for my needs and is weighted and stays at the bottom. I will consider purchasing the larger puck if I need it.

The media could not be loaded. Works as I suspected. This is on low flow with an adjustable valve in the air line. Full blast and my fish would be balloons . Lol joking. Would recommend!

I must turn off at night time but it is okay

Works great in aquarium. Much better bubble action than most. Very easy to install. Design keeps it from logging quickly and can be cleaned very easily.

This nano aquarium air stone is pretty great.It arrives in a tiny branded box with only the air stone puck sealed inside of a plastic frame.The stone works quite well if you soak it ahead of time for a while and as I ordered the smallest one, their measurement is pretty much just for the air stone itself. Not for the plastic housing it's in. So the measurements don't exactly line up to their advertising.Be careful what type of aquatic life you use something like this for as smaller crustaceans, such as shrimp, may catch these tiny bubbles inside of their shells and die because of it. I see no issue using this with any type of fish though.Overall, great tiny air stone but personally I feel it is over priced. At 16$, even with whatever coupon they offer, I can still get a pack of regular stones for less and have a bunch sitting around for back up or to use multiple at once.

This is a great fish accessory to upgrade the air in your tank.
