Ziss Adjustable Air Stone

Great air stones. You can adjust the are bubbles and very easy to set up and just as easy to clean. Saves money on air stones that break and don't last long. I love these air stones.

Will buy again

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
