Some airstones seem to have a lack of porosity, and air will find the path of least resistance resulting in some airstones only bubbling around the top or only in certain sides. These give a uniform pattern from all sides of the stone. Whether using for bubble ornamentation, or to use in an undergravel filter, these do the job well.
I bought these air stones for my 1.5 gallon Betta tank and they work wonderfully. My fish has a steady supply of oxygenated air as well as a mild current in his tank. Great buy!
These airstones work great as long as you don't try to remove them from the airline tubing after they have been used for a while. When you try to disconnect them, the connector often pulls out, making them unusable.
I added these to the air lines for my tank and the bubbles are more relaxing now!
I've bought several products for my Magnum Filter, I had a problem with it and the advise given to me by your rep. saved me from buying a new filter. Customer satisfaction is first rate.
