Review on JW Pet Company Aquarium Accessory by Jessica Redmann

I was generally afraid to buy a bubble stone as the internet is full of bad reviews for such products. This worked like a charm. It stays at the bottom of the tank and has bubbles across most of its width. It helped a lot that I bought a variable speed air pump as it allowed me to adjust the amount of bubbles to my liking. I didn't buy an air line check valve and will need to buy one next time. I was surprised to see that when the air pump was turned off, the water would rise up the air line by itself, which I believe is due to capillary force.
