Bill, I will take a closer look at the boil to see if I can recognize a separate bubble pattern at the surface. The diffusers are 6 inches apart from each other or about 18 inches center to center of the diffuser. If I can identify a bubble pattern at the surface of the water I will build them closer together on the next system. Thanks Bill for your willingness to share your expertise. I'll post some pictures this weekend as to the progress. Thanks.
Bob
