🐠 Pawfly 4 Inch Air Stone Bar Micro Bubble Diffuser - Aquarium Fish Tank Pump, 2 Pack Review

They smelled like strong epoxy. It was overwhelming when I opened the bag with the packages inside. I would never put them in my aquarium.

Two for the price - great. They are good, but like everything else, they have their limitations. I wish the bubbles were smaller and I've since gotten an air stone for another tank that makes smaller bubbles. The size is perfect for my 15 g. I don't see it being used in anything smaller.

I like it very much. Using just one or more small bubbles creates more water flow, so I had to reduce it. All the little bubbles even make a relaxing sound, similar to rain or running water. The only downside for me is that I want the connector to be vertical. Not so hot what's up.

Arrived on time and intact. I forgot to take a picture of the packaging, but you will receive a suction cup and cup clip stone (2 packs 4 inch) in each package. Followed the instructions and everything works great! I love that I can adjust the airflow (set to medium-high in the video) which creates great airflow. Definitely worth it.

Love this aeroston. I have this in my 3 gallon shrimp filled nano tank. When the air flow is increased, many very small bubbles are thrown out. But since this is a shrimp tank, I use a flow regulator to reduce airflow. There are still nice light bubbles to aerate the aquarium, but they are delicate enough not to disturb the shrimp.

1 of 2 working. Works well (as in the 1st photo). The other pushes large bubbles out of a small area of stone - unevenly distributed and makes a loud gurgle, something is wrong with the airflow. No, this is not my pump as I tried the defective one with two different pumps in two different pools. So my ONE replacement arrived and it's broken - the stone itself has a long thin piece of plastic/strip that's partially torn off AND the opening where the plastic tube coming from the air pump is…

I've been using Pawfly for a few years now, they work great but not for long! They cannot be cleaned as they claim. I've spent a fortune on every size available, but I still took the plunge. The seller is very good at refunding you, but what can I say. At least they don't disinherit like most Aerostones. I have 4 aquariums, a must if you have a Pleco 25.5". An experienced aquarist will know what I'm talking about. Also, it's worth knowing that losing power, even with a check valve, will quickly
