randy, i cant answer your question based on the soil sample results, but had a thought (a kind of "in general" thing)......
is it possible to conduct a series of "bench scale" tests on pond water....in other words would a vendor be amenable to selling a small quantity of a variety of chemical and or biological agents with which the pondmeister could test the compounds individually at home.....line up a bunch of mason jars on work bench and test each one? carefully measure the ratio of pond water and testing agent and extrapolate to pond volume when you find one that works? it might help to promise the vendor you'd buy the larger scale amount from him if you find one that works.
