Thanks for your interest in this - sorry I've been in Chicago for the last five days enjoying -40 windchills.
I looked up my well water tests - and found a report for Electrical Conductivity
Here goes:
.754 mmho/cm
Of course I know how to interpret this result, I just wanted to see if Brettski did too - so I'm going to play dumb.
Honestly - not sure if this is what I need.
TJ -- do you have some way to get a conductivity reading from you pond? I think that's has the potential to limit your success. Dr. Bruce, how do you get water quality measures?
