Ziss Adjustable Air Stone

These are the best for nano fish, get teeny tiny bubbles without sacrificing too much oxygen.

Excellent Quality Airstones 👌

To start with I really liked it. After about a month it stopped working . I turned up the pressure no good then I remembered the little washer looking things that came with it I didn't know what they were to start with by then I thought I guess they were like replaceable washers . I didn't know where they were. So the stone was trashed . I bought another one but it ended up in the trash also too much trouble changing washers all the time. I had rather just put in a new one for just the air and be done with it

The only gripe is i wish it was a little heavier. Other than that. This thing will last 20 years. I appreciate the wide range of bubble size you can create by tightening or loosening the stone... you won't regret it...

I bought this air stone a couple months ago but decided not to use it since I bought an AC sponge filter. I read that it wasn't needed since the filter has an air stone. I bought a another tank with a HOB filter, so decided to try out the Ziss. Very disappointed. It's NOT weighted, and after a couple minutes it stopped bubbling altogether. Will not buy another.

I bought this out of curiosity. I like the idea of an adjustable airstone, plus I liked that it was weighted. But last week it came in handy, it made the perfect replacement for a tiny sponge filter that needed a better airstone. The cheap blue pumice airstones I already had were too wide to fit... It really saved the day!

Works well. Like that I can change the filter in the middle great for new fry tanks. Great quality.

Work great

Although they require a weight or held down by something in the tank, the flow of air creates plumes of bubbles. I also use it inside the sponge filter. And when the pads become clogged, they are easy to quickly change.

work great, best I have used in 55 years keeping fish aquariums. very easy on air pumps.
