🐠 Enhance Oxygenation and Aesthetics: PIVBY 4.2-Inch Air Stone Disc Bubble Diffuser for Aquariums, Tanks, Ponds, Hydroponic, and Aquaponic Systems Review

Secure to the bottom of the aquarium using the suction cups provided. Produce a ton of bubbles with little energy required by an air pump.

Product blisters although the product I received looked used and scratched and the box arrived used, sealed and damaged. Can't fully rate this as it doesn't work because it arrived broken.

Pros: They're not terrible. Cons: Large bubbles. Too light to use without the suction cups and the suction cups are awkward to use and can hide bacterial growth spots in the DWC. Air connection direct instead of angled. Kind of expensive.

I immediately noticed that it cannot be washed as the description says. Put it in the aquarium, it seems to be working fine, not a lot of bubbles as expected. The only reason I chose them over many others is the laundry facility. Not happy at all.

I like 3 suction cups, they hold up well. I bought two of these as I no longer need the large air stone at the bottom of my tank, I have actually installed both in the back of my tank and they look great, have freed up a lot more space for my discus and are producing quality bubbles. I am happy with the purchase.

I have a good sized air pump rated for a 150 gallon tank so no air supply. Just don't make bubbles like the picture. I was not impressed at all with these air stones, will never buy them again. The rod air stone is much better and spends hours trying to get these even and somewhat hidden, totally impossible, I will never buy two round stones again. Use an air stone with entry holes on both ends, they work 100x better.

I don't know why there are so many negative reviews but I hooked them up yesterday, they work great. Love the fact that they have suction cups so I can attach them to the bottom of my 125 gallon tank. I bought a Hygger 160GPH 5W Dual Outlet (4mm) adjustable aquarium air pump and not only is it insanely quiet but you can adjust the airflow and at high levels the bubbles are just what I wanted from my tank. The price is good for 2 pieces per pack and I will definitely buy them again.

I purchased 4 of these air stones in March while building a hydroponic system. I had to move away from the congregation for about a month, but today I decided to wrap things up. When installing the pneumatic stone, the nozzle broke off without pressure. The airline was merged and. It was placed at the bottom of the system. The air line immediately moved to the top of the system while the rest of its air stone stayed at the bottom. There is no replacement part as the entire plastic part of the…
