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.

The media could not be loaded. 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.

I’ve had this bubbler for a while and bought based on the reviews because otherwise it’s pricey for an aerator! I’m writing this 2 years later to say that this things is amazingly robust and has made a would of difference in my take water. Turtles and notoriously messy eaters in the water and this bubbler along with turtle sludge destroyer has completely changed my tank’s water. This bubbler has not lost its level of micro bubbles nor broken down like other air stones have done in the past. Bonus pints for the fact that my turtle LOVES to hang out on top or it and seems to enjoy the bubbles. Maybe like a massage or something? Highly recommend this item!

The glue holding the air stone to the base went bad after a week or so of use in a fish tank. Unacceptable given the staggering cost of these stones versus other lower cost alternatives. Save your money.

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! :)

But the whole stone doesn’t bubble like that. It only puts out a qrtr of what’s in the pic

I purchased this to use with the new air pump. Together they are great. The fish are much happier and the tank stayes cleaner and well oxygenated. I am very happy with this stone as it has it's own appeal it the tank. My grandson loves volcanoes and the bubbles rising in the tank looks as if he has an active one in there.

After reading some other positive reviews, I have concluded that much with these Hygger pumps is in the ear of the listener. I find them too noisy, and too much noise in the aquarium is unacceptable. I have found all "nano" air stones to be noisier than the traditional ones. If I were a scientific researcher, I would secure funding to compile data, but all I can leave you with is anecdotal evidence, my experience. The bubbles are pretty, but I am unwillingly to exchange the contentedness of my two goldfish for viewing pleasure. After all, I'm around for an hour or two gazing at them and making chirping noises. They have to live in the tank, and I want it to be as quiet as possible. So it's the good old, tried and tested giga stones for me.It pains me to leave anything negative about any product made by Hygger. In my estimation, it is one of the most venerable brands out there, sharing top rank with Eheim. (My 4-star rating is out of respect for the brand.) The air pumps Hygger makes are absolutely the best. Solid and quiet and powerful. I highly recommend them. But these stones suffer from the rush to market the latest new "nano" devices. An air stone is not an Intel chip, and my ear tells me it is best to leave something alone if it isn't hissing. Sticking to the tried and true and to tradition, after all, is one of the things that makes a venerable brand venerable.
