Noncarbonate Hardness?

[funkenet]

I am trying to figure out my water so I can make the right water adjustments with confidence. (normally I just throw in a TBS of mash stabilizer and cross my fingers. I have figured out most of it but I'm still missing a few things. I am hoping that someone with more knowledge than myself can figure out the missing numbers with the info I have gathered.


Calcium hardness: 50-60ppm
Magnesium hardness: 40 ppm
Noncarbonate hardness: 30-50ppm (I am not sure what noncarbonate hardness is)
Bicarbonate hardness: UNKNOWN
Sulfates: 21.9
Sodium: 8.7
Chloride: UNKNOWN
Total Hardness: 302.5 mEg/l

Any help with this is much appreciated .

non-carbonate hardness is permanent hardness, the cations which are bound to non-carbonate anions (eg sulfate and chloride).

its also commonly referred to as 'general hardness' in the tests i've seen.

My city doesn't do bicarbonate measurement, unfortunately. I poked around a bit and found the following, which shows how to calculate bicarbonate from total alkalinity and pH. I'm no chemist, but the calculation looked good to me:
