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

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.

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

Great product!

I think this is a little on the expensive side.I’m happy with the item just not so much with the price. It isn’t that much more impressive than your average bubble stone.It gives off a nice amount of aeration and surface disruption. And the suction cup that it comes with is handy for keeping it in place. That’s about all I have to say about it. See... not that impressive!I’ve always used the $2 bubble stones from Walmart and secured them to my tank wall with suction cups and sewing thread. I get the same amount of bubbles with two small stones and they’re quieter than this more expensive one.

I like this air stone a lot. I got a 2 inch for my 10 gallon tank with a betta, I have to turn it down a lot since they are not strong swimmers. Probably 2 of the 1.25 inch would have been better.Lots of very fine bubbles come out. Some brown algae is in my tank and it is impossible to get completely out of the air stone surface (since it's porous) but most of it you can get.The reviewer saying the fine bubbles stopped and had water coming out of one side: I had the same thing happen after mine backflowed. I got another one and put the pump above the aquarium. If it happens again then I'll have to change my review since this is too expensive of an air stone to get ruined by one brief backflow.

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.
