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.

I have many other Hygger products that I really like (pumps, lights, foam filters) and two of these air discs in my tanks & they work great, so I knew something was wrong when this one was not bubbling. Contacted Hygger directly and after a little troubleshooting they are sending me a new one. Easy-peasy! Hygger makes such great products at reasonable prices compared to others -- now I also know they have great customer service that stands behind those products. I highly recommend! :)

I really like this air stone, I ended up buying a second one. I didn’t soak it for two hours and it still worked amazing the second it was in the tank. I have them hooked up to 40 gallon air pumps. Love the look of them and the bubbles are gentle enough that my goldfish love swimming through it.

The product is not working the way it said. No bubbles are coming out of the puck.
