Pawfly 8 Inch Air Stone Grey Mineral Bubble Stone Bar Diffuser Bubbler Airstones for Air Pump, Aquarium, and Fish Tank

Some reviews said it didn't bubble much. Don't know what the problem was, but mine produced lots of very small bubbles even on a lower setting of my air pump. Maybe their pump was the issue ? I'm very pleased.

This airstone bar is amazing! It creates a beautiful, fine mist that's perfect for my aquarium. Easy to clean and durable, too. Highly recommend!

This is my second stone like this. This one is th worst. Will not be buying again. Useless.

This works about as expected. Only complaint I would have is that the bubbles are way bigger on either end of it, instead of the tiny micro bubbles that you get from the rest of the stone surface. Otherwise, works great, tiny bubbles, oxygen for the tank, etc.

It works, it makes the bubbles. Great price for the product. Easy to set up. Seems like it will last for quite a while.

Just ok. Product seems very fragile and may have been damaged during shipping. We'll see if the replacement works any better.There is a hairline crack across the middle where large air bubbles escape and prevent uniform smaller bubbles along the full length. I set a piece of coral over the crack which helps disperse the air bubbles.

Just what I needed for my small pond. Bubbles diffuse wonderfully.

I ordered 2 of these. The 'intake' was broken off on 1 of them even though the package had not been opened. It would cost $9 to return an $8 item so I lost $8, a sizable amount for a senior citizen on a below poverty level income. Avoid buying this item.
