About this item

  • 🐟【Fine bubble】 Oxygen stone refines the air output from the air pump into a particle bubble, which is smaller and denser, like the “atomization” effect, and the bubble size can be adjusted, and the different oxygenation amount can satisfy different use requirements
  • 🐟【High dissolved oxygen rate]】 Compared with ordinary bubble stone, the nano bubble stone emits more bubbles, and the gas and the water surface are more widely contacted, which makes the dissolved oxygen amount larger
  • 🐟【Quality Nanomaterials】: The nano-stone is sintered at high temperature. The material is sturdy and durable. It can be used for a long time and has better dissolved oxygen effect. When the bubble burst into the water, the sound is super quiet
  • 🐟【Air pump wattage】 The weighs of air stone is 15.2oz/430g and is easily placed at the bottom of the fish tank, suitable for fresh water and salt water. It is driven by an air pump of 4 watts or more. PS: The deeper the water, you may need to use a larger wattage air pump to drive it
  • 🐟【Air pump accessories】: 4 inch nano air disk stone, 1 control valve, 1 check valve, 2 suction cups, 1 T-shaped connector, 1 reducer of connecting 8mm and 4mm. Note: Hose and air pump are not included

Second, I have an absurdly small tank. My <10gal air pump is literally overkill for it, so I have a valve to adjust flow to my airstone so it isn’t blowing the water out of my tank rather than oxygenating it. My old airstone wasn’t having a great time and long story short, the bubbles it was belching out sounded awful, and if I was annoyed by the noise it was making, I can only imagine how fed up my shrimp were with having to live with it.

So, I started my hunt for a new airstone, sold my soul to Bezos, and found myself the proud new owner of a Hygger Airstone S35 (1.25″).

It’s only the beginning of my and my shrimps’ relationship with this airstone, but our first date was better than expected. Maybe the Amazon interface is designed in a munipulative and intentionally convoluted way, maybe I was just too blinded by my conflicted emotional state in supporting a service that fails to support and empower its own employees and small, individual vendors it plagarizes from….I digress. I didn’t realize how much more I was actually going to receive with my airstone purchase! A control valve, suction cups, check valve, a freaking t-connector, and a reducer on top?! All I meant to purchase was a practical airstone that would quietly blow tiny bubbles (honorable mention to the small user manual for including a tiny and adorable ‘application diagram’ including a supper table and Nemo) and Hygger delivered that and more!

Finally and most importantly though, is that my shrimp appreciate the new air stone. They’re mildly concerned about the white colour — because algae will inevitably leave its mark on everything — and that it wasn’t the agreed upon <1″ stone we discussed… but ultimately, the airstone makes up for it in adorably tiny and peaceful bubbles as advertised! A few shrimp are currently enjoying a serene bubble bath. I find myself checking to see if the airstone is actually working because it’s so quiet compared to the old one. Very happy with the product so far.

Tldr: So far so good. It works as advertised and I would recommend. Be ready to scrub the stone regularly as algae will easily discolour it (unless you prefer a more natural algae-chic look) and have some appropriate superglue on hand if ever the stone pops off the base.

Overall I’ll gladly pay 19.99 for the 2” model and 24.99 for the 4” model, it’s a very well designed product, doesn’t feel cheap by any means and does what it’s supposed to.. hopefully my video can help and prepare others for the sizing as I would’ve got the 2” if I knew how large this one was.. still a great product!!

I’m still really new to aquariums and such, but I know this works because bubbles come out but they only come out on half the stone? Is this like a thing? Will it go full after time? Only the future can tell… and I will update when I find out if it’s just my stone or if this is how it’s supposed to be.

Either way – the bubbles are very small and seem like they’d be a good time if I were a fish.

Just an added note: you’re going to need an air pump and tubing to make this work and they do not come with this air bubbler. But this air bubbler does have a lot of attachments that go to it so it shouldn’t matter which one you pick up.

I’m also shocked at how heavy this thing is. And it’s big. Overall, I think it’s pretty awesome and I’m pumped (get it) to add it to my aquarium!

In the past I wasted money on several air stones only to be disappointed with the performance because they produced large bubbles which the fish seemed to avoid.

The only deficiency with this product is that about only half of the surface of the stone is functional.

Had I known this I would have saved money and purchased the smaller size.
