Aquarium Air Stone, Bubble Stone Fish Tank Oxygen Ultra Silent Deep Dissolving Oxygen Diffuser Kit for Aquarium Fish Tank and Hydroponic

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.

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.

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.

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.

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.

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.

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

I tried a few different types of air stones and for small bubbles these are the best no contest. The standard air stones bubbles are way too big and half the time they leak more air from the connection then goes through the air stone itself. These are fantastic, the bubbles are tiny which is exactly what I wanted. No leaks: all the air goes through the air stone. Comparing to a standard air stone in my tank beside it the air bubbles are about 1/50th of the size there is just tons more of them (using roughly the same amount of air). This makes it much quieter and more gentle which is great for small tanks. I wish there was a 1 inch version but otherwise this is my perfect air stone. Will have to see how it holds up over time ,very happy with my purchase so far. Will be buying more!

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.

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

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
