boxtech Aquarium Nano Air Stones, 3.2 Inch Aquarium Ultra-High Dissolved Oxygen Diffuser Bubbler, Nano Oxygen Aerator Stone for 30-70 Gallon Hydroponics (80 MM)

This made a lot of difference to my tank and the fish love it

Good aeration at a very reasonable price

Exactly like the picture advertise (surprisingly) this is the 4th aristone I've gotten all my others including a hygger one have been a massive let down with the size of the bubbles and the noise. Really happy with this one

Absolute rubbish not even half was bubbling. Don’t buy waste of money. Can’t send it back as I have cut the pipe.

The media could not be loaded. This air stone is absolutely amazing! I got the 150mm size and it pushes out a constant huge stream of tiny bubbles and super oxygenates the water. My ranchus won’t leave it alone and all six of them are swimming in and out of the bubbles all the time so they seem to love it. Highly recommend! It took about 15 minutes for the stone to get to maximum bubble output when I first put it in so be patient and let it do its thing. Really reasonably priced for the size, the air stone is nice and heavy and comes with suckers to hold it in place on the glass. Buy one!

Absolutely great for a few weeks, excellent output of minute bubbles, sadly it then becomes the same as an ordinary air stone with larger bubbles

Works really well. I found that the bubbles weren’t as fine as shown but that could be because I have mine under the substrate rather than sat on the top. But I can’t complain I have 2 pumps running on mine and it moves water really well.

Like advertised but the tub is to thin for my pump and don’t have an connection for a larger pump . I wasn’t able to see in action
