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

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.

Noice little bubbles

These work great! I like how they stick to the glass.

This diffuser looks good and produce nano bubbles without splashes. Only downside for me is the disc is so big but the area that produces bubbles seems limited. The picture shows maximum air to it from my air pump. The same setting on an air wand would produce so many bubbles that it would splash everywhere. Even if that wand is placed at the bottom of my aquarium. It seems like the amount of bubble generated is inconsistent between different units unless over time the disc decays and more air come out. I guess if this was in a 2-5 Gal tank, it would do the job and look nice. The diffuser does turn brown and green after a while. [Updated] I have changed my review to 5 stars. It looks like my air pump was the culprit of the low amount of bubbles after all. I move this diffuser to another pump, and it is working properly now. I actually have to lessen the amount of air into the diffuser. [Updated 11-21-2023] After 3 months of use, the diffuser is brown. Lowering to 4 stars as it is still functional but just unsightly. Also the suction attachment that holds the diffuser is completely flat.

looks super sleek in my aquariums, i bought two

This little air stone sacred out so quiet! I was like, whoa! I gotta have more of these! It was perfect for the aquariums in the bedrooms. The size is somewhat bulky and takes up more room than I'd like in the tank but it was so quiet! My 1st turn off for ordering more was the price! NOT worth more $5 in my opinion... so I thought I'd wait for a sale. In the meantime this little contraption started to change. As the stone gets acclimated to the water it gets louder and louder. The algae seemed grow faster on that stone than on my others. I've tried cleaning it but that's difficult given the shape of the product and how it's made. I got this product hoping it would be quieter than other stones, as advertised, but that feature only lasted about a month or less. Overall. I'm somewhat disappointed but it still oxygenated the water for me so it's not s complete bust!

Works as described very good price would buy again

Very fragile and thin plastic. Did not like it. The first one was delivered crushed and broken in the box . Replacement arrived and it looked very flimsy. All it takes is two fingers to pinch it and it will break. Would not recommend.
