I found out in one of my local lakes they use a static tube diffuser. I was wondering, what is thier claim to fame?(Are they any good) I think they are pumping around 35cfm through it so it is a big system. I have never heard of these and thought I would share. 120ac lake, diffuser 25 feet deep with 200 feet of 2" poly feeding the air. This system keeps a massive hole in the ice even with our nasty winters.
