Bill I will check again but I thinks they use a different dffuser now...more like vertex. One thing I like is I can put in on the deck with no encloser needed. My deck runs right down to the pond and could tun tubing under the deck straight into pond. I will check the diffuser again. Thanks for the info. I think I am finally getting the hang of things. Oh and the price is really good. Checked and they use an airBASE round membrane diffuser.
