I think we have to be a little careful here when we discuss degrees and ppm
with water hardness.

Degrees DH (German) = 1 part Ca Oxide per 100,000 parts water = 17.9 ppm.
Clarks degree = 1 grain Ca carbonate per imperial gallon.
American degree = 1 grain Ca carbonate per 1,000,000 parts water.
PPM = parts Ca. carbonate per million parts water.
