Love it!
Great Air Stone – Excellent Bubbles & Oxygenation! I recently purchased this aquarium air stone, and it has made a huge difference in my tank’s water circulation and oxygen levels. It works perfectly, creating a steady stream of bubbles that both my fish and plants love! Strong & Consistent Bubbles The air stone produces a fine, even bubble distribution, which helps aerate the water efficiently. My fish are more active, and I’ve noticed an improvement in water clarity and oxygen levels since adding it to my tank. High-Quality & Durable Made from sturdy, non-toxic material, this air stone is built to last. It’s well-constructed and doesn’t clog easily, even after extended use. Plus, it’s easy to clean when needed! Quiet & Easy to Install I was impressed by how quiet it is compared to other air stones I’ve used. Installation was a breeze—just attach it to my air pump, and it was good to go. It fits perfectly in my aquarium without taking up too much space. Perfect for Any Aquarium Setup This air stone works great for both freshwater and saltwater tanks, and it adds a beautiful bubbling effect that enhances the overall look of my aquarium. Whether you have a small or large tank, this is a fantastic addition for better aeration. Overall Verdict If you’re looking for a high-quality, efficient, and long-lasting air stone, I highly recommend this one! It improves oxygen levels, keeps fish happy, and adds a great visual effect to your aquarium. ⭐ 5/5 Stars – Excellent Performance & Value!

Several shrimp, a ramshorn snail, and several aquaric plants approve of this product
Firstly, unrelated to this store or its products, I dislike Amazon and try to avoid ordering from it 99% of the time. I'm a dork that tries to buy from relatively local brick and mortar stores or try to make an online purchase from the later..... But gez man! Tiny airstones seemed to be actively hiding from me at my local pet supply stores lately, and so here I am! 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.

Very fine bubbles and very quiet operation.
Larger base than expected, bubbles are very fine when used with a decent volume air pump. I recommend an air pump that has adjustable outflow to tune it in to your desires. As theses bubbles are so fine, it is best for dissolving oxygen in the bubble column rather than using it to create surface agitation, as the bubbles are so gentle, they won't move a lot of water, but this also makes it very quiet. Overall works very well as a fine misting air stone in a room where noise consideration is important. Been running for 3 weeks with no issues at all.

Works as advertised.
This is a recent purchase that actually works as per the description and I will be ordering another for a second aquarium. The bubbles are extremely fine and almost effervescent, such as seen after dropping a seltzer tablet into water. The effect is almost mist-like which should help with the dissolved oxygen content of the water. I purchased the smallest one of this line and it is on low power in a 5 gallon tank. My other is a 10 gallon. It comes with everything listed in the advertisement and also included about 2' of what appears to be high-quality rubber tubing for the air pump. It is very quiet and is heavy enough to rest on the substrate without moving. The only change that I would make to the design is that I would make the airline input horizontal rather than vertical. The airline tubing could be more easily concealed beneath the substrate or behind aquatic plants. I can't comment on the durability since I just installed it last night but their cleaning instructions advise to soak and brush until bubble density is restored. I hope it lasts a long time before having to replace. I have not seen such tiny bubbles since I was using a CO2 injection system. This product is a good find for me.

Does not last even 4 months.
Bought in Feb 25, it is now May 25 and I have had to toss this stone. I was wonderful when I first got it, excellent, fine mist of bubbles. You would think that with such a profusion of bubbles that nothing would cling to it - but you would be wrong. This thing attracts green algae like an over turned peanut truck attracts squirrels. I kept after it, scrubbing with a toothbrush, but nothing could keep it clear and as of yesterday, the stone was shot. Pretty expensive for something that you need to toss out after less than four months of use.

La verdad es que si sigues las instrucciones está súper, efectivamente si puedes moderar la cantidad de burbujas que salen y sin problema. Solo tienes que comprar la manguera por separado pero cumple muy bien su función.

Great bubbler! Even running at 75% air power (I put a control valve in the tubing) the bubbles are very powerful and tiny, and it fills the water with oxygen!! I can tell my fish are very happy to have so much air to breathe now. Beautiful product! And a bigger airstone than I was expecting. It has a very heavy base and

Me parece muy bueno el tamaño para acuarios pequeños, si saca unas burbujas muy pequeñas, tendré que ir vestigar como limpiarlo
