hygger Aquarium Air Stone, Fish Tank Bubbler, Nano Furnace Flue Air Disk, Bubbles Exquisite and Ultra-High Dissolved Oxygen, with 2 Suction Cups, 1 Adjust Valve, 1 Check Valve (2 Inch)

When I first got this bubbler I was excited and put it into the aquarium to soak as instructed. After leaving it in the aquarium overnight I attached it to the pump and it did not work(sad face). I left it in for a day and it did not work. Purchased a pump for a 100 gallon aquarium and behold it worked. I had had a pump for a 75 gallon aquarium. Now my turtle loves having a bubble bath and reorganizing her aquarium. I love these bubblers and recommend them to anyone with a larger pump.

My kids love bubbles, the idea of micro bubbles intrigued me. Decided to give it a try since I have a tank without a bubbler/air stone. I ended up soaking it overnight (my day got busy before I could mess with my tanks), and I finally dropped it in today. Because I was too lazy to get a nicer pump, I dug out the cheapest one Walmart sells to use. It came with an antisyphon valve and a flow regulator (if you use a more powerful air piling) to control the bubbles. At first I dropped it into the middle of my tank, but the flow from my canister filter pushed the bubbles too much, so I moved it to bubble directly below my outlet. I’m sure I’ll fiddle with it a bit more, or move where my canister points to make my tank awesome, but that will Be later. Anyway, the stone is awesome. It is ridiculously HEAVY, so it stays put once you have it where you would like it. It came with suction cups to route the tubing, but I didn’t need to use those (yet). The micro bubbles are quite mesmerizing to watch, I cannot capture it on video. But it’s like watching cigar smoke dance through the air the way the bubbles dance on their way up. I may need a second or third stone and use them as decor. Also, make sure the stone is under the water before you turn it on, otherwise you will get a wet surprise! I did soak mine in a dish of tank water before use, not water from the tap.

We have had this product for just about three months now. The bubble effect is fantastic and puts out a great amount of air. The issue is with the algae buildup on the stone itself. We go to Great Lengths to keep our tank clean yet algae has built up on top of the Stone. I have taken great effort to clean the top of the unit with hot water and a scrub brush but I don't want to expose it to any chemicals. Despite my best efforts the bubbler still has green algae spots all over it. It is quite unsightly to have a well maintained tank with a nice white bubble apparatus yet having it covered with algae. Very unhappy with the product and if I had known this was going to happen in this short of amount of time would definitely have purchased a different item. Definitely not worth it for about three months of use for the price. The reviews mention how well it works which it does but not how impossible it is to clean it. I'm not necessarily saying a more expensive one would be better or a less expensive one would be worse but check out all the options available before purchasing this one. Since I'm past the return window I can't send it back and now I'm stuck with a disgusting piece of aquarium Hardware that has to be replaced when it should have lasted a bit longer

I brought this four years ago. It still works very well. I brought another fish tank so I’m going to buy another one. I love that you can adjust the bubbles. Great buy! No noise . I have it in my 30 in tank .

It's going to stick out in your tank. The stone is also not going to evenly emit bubbles. Depending on whether you are using this for co2 or just oxygen, you're better off just trying to go with a CO2 reactor or an online CO2 diffuser.
