On fresh water, unity for EC is microsiemens (10 from 2000) and millisiemens for sea water (20/80).
But with fresh water it also depends on type of tank, e.g. Discus needs
A. 80 à 150µs (breeding),
B. 200 à 250µs (adult),
C. 350 à 400µs (sub-adult),
For TDS , 2 µS/cm = 1 ppm.
May be, each one could choose his own figures to determinate his graph?...
