Features 5

  • 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 5.2oz/150g 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 2 watts or more. PS: The deeper the water, you may need to use a larger wattage air pump to drive it

They listened carefully to the owner of the fish farm explaining the characteristics and breeding requirements of various ornamental fish, and found that behind the beautiful has a careful care! This aroused everyone's strong interest, so they decided to explore the road of aquarium together. hygge is generally translated as "comfortable cosy". hygger is derived from hygge.

High quality. Perfect for small aquariums.
Size: 2 Inch
Outstanding product for small (~10 g) tanks. I have a small hospital aquarium in the theater room that needed a new aeration stone. This one is great! Solid construction with a good weight (so it will stay at the bottom of the tank). It was a good price and came with all the tubing, check valve, splitters, etc. A very good product. The nano bubbles are exactly what I needed for this small aquarium. ... show more

Several shrimp, a ramshorn snail, and several aquaric plants approve of this product
Size: 1.4 Inch
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. ... show more

Powerful Little Stone
Size: 2 Inch
This thing puts out a lot of bubbles. I really like how it looks and my fish, so far, seem to appreciate it. The only drawback is, the bubbles are so fine, that, it makes my tank sound like it's fizzing. I don't mind it but others might not care for it. Other than that, I love it. I actually have 2 of them in my 125G tank. ... show more

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! ... show more

Lasted about 5 years
Size: 4 Inch
Decided to do a review today as one of my stones started to have issues. I purchased the first one 5 years ago and the second about 6 months after. I did that so I could more easily swap them out while cleaning. They were the 4" versions. They would accumulate algae / diatoms over the course of a month or so. Easiest cleaning method was to take it out and soak it in a water / bleach solution (vinegar works also but not nearly as effectively/quickly) for an hour or so, then rinse well and soak in water+prime, rinse, let air dry. Having two made it simple - just swap to a clean one during a water change then soak the dirty one. I saw some reviewers saying their stones grew "mold" or discolored. Pretty sure that's just algae and / or diatoms. One of the pics is definitely brown algae / diatoms. That happens in a tank, no matter how established / clean, especially visible on a bright white air stone. The issue with mine (the 5 year old one) is that after the most recent cleaning, I started to see a few sand particles coming out of the inlet nozzle when rinsing. Also started to hear some rattling when shaking the water out. Decided to take that one apart just to see what was inside (see pics). Looks like they are two pieces - the top cover - a fine white diffuse stone and a portion below / glued inside, which looks like a slightly more course / sandstone type diffuser. Its possible that 5 years of bleach soaking started to break down the course stone inside, but not complaining as I mentioned - it lasted 5 years and my other one is still fine. Probably order another one to continue my monthly swaps. ... show more

Does not last even 4 months.
Size: 2 Inch
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. ... show more

Bubbles aren't what was expected
Size: 4 Inch
I let the stone sit in water for two hours as directed, and after hooking up the bubbles are not what I expected from the picture. The WalMart Small Blue 4 inch air stone bars put off more bubbles then this, and are 10x cheaper. Very dissatisfied. The stone is heavyily duty made, good quality, heavy enough to stand at bottom on its own, just not enough bubbles. I have it straight connected to my air pump so nothing is restricting it. ... show more

Aquarium Saving Grace
Size: 2 Inch
I have a 40 gallon tall aquarium. I've had issues with it crashing and killing my fish since I've had it. Wanted to scrap the whole aquarium because of the issues thinking it's AIO design was the problem. I've added 2 sponge filters and a hob filter to the sump itself. The water is definitely well filtered and yet, despite my efforts I had another crash after a minor water change. Did not change media at the same time and I used bottled spring water. I can't trust my tap water even with prime conditioner. Saved only 4 fish from the crash out of like 20 schoolers and put them in my 10 gallon. Oddly enough my Opaline Gourami who I couldn't move due to his large size was fine. I thought he'd die but he lived and thrived, gulping air at the surface occasionally but resting comfortably in his claimed cave near the bottom. I didn't understand why my gourami remained healthy in the crashed tank while all but 4 of my school fish died until it dawned on me they're like bettas and breathe air. Despite my bubbling sponge filters, there wasn't enough oxygen especially being a tall tank. There was so little oxygen, not even my pest snails could survive. This bubbler has changed things immensely. The bubbles are very fine and make the water fizzy at the top, properly oxygenation the tall water column without introducing extra turbulence in the water that could stress my small scooling fish. This let me readd new fish to the tank and so far, they're relaxed and eating well including my bottom dwellers. Plants that were dying or melted have come back, some I don't remember planting or thought were long dead. Even my snails are back and slowly repopulating. It's quite. It pumps in a lot of air at full blast. It keeps my fish alive and well. Without this, I would've tossed the tank when my gourami would pass. I can now enjoy my tank and pray I don't have another crash ... show more
