Rikko, tell us a bit about how you have the outlet of the surge enter your tank. Does the pipe sit submerged, or above the surface, or midway, etc. Also how many bubbles do you get from it?
I briefly toyed with Borneman surges myself a couple years back but I didn't quite get the effect I was hoping for. I'd love to get more height on the reservoir and try again, but more height means more air in the discharge tube so I see a bit of a catch-22.
PS. Get a buddy to come over and snap some pictures!
