[APD] Water Quality Terminology
Yes, its me again, with more questions, but I promise these are the last
ones for a while (until my next idea/problem arises that is! ;-)
I was looking at my city's (Brisbane) water quality data, and some
terminology confused me:
It listed the Total hardness (as CaCO3) at 114 mg/L. No problems there,
But then it went on to list the Ca (as CaCO3) hardness at 58mg/L and the Mg
(as CaCO3) hardness as 56mg/ml. Is the combined total the hardness we call
kH? I thought that Mg contributed to gH, not kH. I am a bit confused here.
Also, would CaCO3 be better at adding Ca in PMDD than CaCl2?
Thanks again for any help,
