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

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 .

When its new the bubbles are very fine, now a month old, the bubbles are less fine, algae in the surface, maybe the cause. Its a good airstone whatever.

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.

This thing performed wonderfully for the first month or so, and then of course it started to collect algae. I cleaned it the first time with just water and a scouring sponge, and it restored the function pretty well. A few weeks later I tried cleaning it again, but this time it seemed so clogged that it would not clean up and/or function at all. I was ready to toss it, then read one of the reviews about using vinegar or hydrogen peroxide to clean it. I soaked it for about four hours in hydrogen peroxide, pulling it out a few times to scrub the surface. Then I rinsed it really well and let it sit in well water overnight. The next day it still would not produce any bubbles, but I took the hose from the pump and blew really hard through it for several seconds ( repeated a few times). All I can figure is I was able to dislodge the algae that had gotten into the stone ( I couldn’t see anything), and now it works like it did on day one. Next time I’ll try just blowing it and see how that works. I like the fact that it stays in place on the bottom, I’ve tried others that end up floating despite the suction cups.
