Maybe I missed it in skimming, but what size pipe was Sepp using for the "Monk?"

I kinda wonder if it is nothing more than the water has a maximum of dissolved oxygen at that point, and that is what makes the fish so lively. My impression is that Sepp thinks there is more to it.
Where is that video Joel? I would really like to watch it. All I have picked up so far is that he likes to use pigs to stomp the ground... they seem to compact it and bring about waterproofing somehow. I would love to use no liner.. so expensive. Problem is my rocks absorb water so would have to blast them away to seal effectively.

Not sure if this is the thread, but I just watched the video about sealing ponds with saturation & vibration.
Sepp Holzer talks a little bit about the Brazil nut effect in that video, but doesn't speak of it by name. He talks about rocks and sand working their way up to the surface as things are shaken. More importantly, though, clay and silt will work their way down, for precisely the same reason; if there are too many coarse particles, the coarsest layer can be skimmed off and more assorted soil put in its place.
I wanted to provide links to more info on the mechanisms involved...especially for anyone who is having trouble following Mr. Holzer's reasoning, or wants more theory behind their efforts to adopt his methods:
Brazil Nut Effect
Notice in the picture at the bottom of the second article, how the largest particle (the sewer system) has worked its way upward, forcefully enough to tear up the pavement. The caption mentions buoyancy, which certainly played a role, but I doubt that is the whole story.

Devon Olsen wrote:ok, thanks, so if one doesnt want to or doesnt have a stream beneath the pond period, it would be acceptable to have a monk that doesnt move?
or is it for some reason a requirement ot have it move around for some reason?
