boxtech Aquarium Air Stone, Fish Tank Bubble Diffuser High Dissolved Oxygen Airstones for Air Pump Accessoriess with 1 Check Valve, 2 Suction Cup for Aquarium Pond Hydroponic

Great stone for my fish tank. I like the softness of the bubbles. The only problem I had was one suction clamp broke and the other wouldn’t stick so I have to order more of them to use this again. It floats if it’s not attached to the side

Works as described very good price would buy again

the bubbles are so fine and soft my beta loves it

It’s very nice, super easy to set up and powerful. I loooove the aesthetic of it and my fish seem to enjoy the bubbles. It did brown out pretty fast on the top but I think that may just be my tank because it’s been having some algae problems. Beyond that though, it’s a good size, pumps out mega bubbles with a very little pump, is not super noisy and is just a good a great addition to the tank

Works well at first but wears out quickly. The first week or two, it worked beautifully. It is NOT silent and makes a faint whistling noise when it's going but nothing too egregious. After a couple weeks though, it wore out and the bubbles are no longer fine. It's more a typical air stone. I guess I shouldn't be too upset for the price, but I was hoping more than a month out of it.

It is super quiet, has truly fine bubbles, didn’t disturb fish or shrimps. At first I was worried, it did produce only two very weak streams of bubbles but in about 30 minutes it reached its full surface bubble production 😁 I love it and would definitely order this air stone again!!! Paired it with hygger ultra-silent mini air pump HG-971. Update: just added a new picture it the air stone. It looks nasty and impossible to clean but it is still works great. Update 3/26/23 the air stoneworks only 1/4 of its surface, leeks large bubbles from its base. Had to connect a different air store just in case if the base will get disconnected while i am not home. Very disappointed, I really loved the tiny bubbles. Update 8/18/23 took it apart, bleached and glued with a flourish glue 2 months ago. Looks and works great.

When you have an aquarium you know that water aeration is necessary. This boxtech air stone provides the aeration my fish need completely silently and efficiently. It hasn't moved a millimeter from the spot I put it in back when I bought it; the suction cup is holding perfectly. It's a very economical and essential addition to my aquarium setup. Completely happy with it.

Great bubbler and love that the attachment piece adjusts flow.

Product is as shown! Really minimizes the bubbles to not disrupt your tank/fish as much! Also quiets the noise coming from the pump!

These are small but they work great in my 10 gallon and 30 gallon fish tanks. Great buy, had both of them for at least 6 months with no problems.

Très joli dans l’aquarium mais trop petit pour ma 20 gallons

Using for compressed Co2. Much better than others I've tried. Nice micro bubbles. Also, it's a one piece design, so no leaking at joints. That does mean you can't disassemble and clean/replace parts such as the stone, but then the others I've tried that do come apart are pretty much garbage anyways because they always leak. Would have rather have this disposable unit once it gets too dirty but that works properly up till that point.

Algae forms very fast on surface
