Ziss Adjustable Air Stone

Ziss Adjustable Air Stone

I really like these and unlike the blue stones I can never get cleaned out these you can replace the little filters or give them a good washing and they work again.

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 👌

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.

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.
