This thread reads like you guys have things pretty well figured and calculated closely to what is really occurring with Mike's system.
The only thing I would add or modify to my prior post of several years ago is the amount of DO that is needed on the bottom sediment areas. I currently think 5ppm is more than adequate for good invertebrate and bacterial decomposition of bottom sediments. IMO Good decomposition of deep water sediments can occur in 1-2ppm dissolved oxygen at the sediment water interface in the pond's deepest water "belly". However if you want good fish diversity of all species living in the deep water area of the pond then 4-5ppm dissolved oxygen is needed.
Unless there are some specific questions I won't need to add anything else.
