water hardness

I just found the hardness of my water as reported by the city listed as "212 to 410 ppm (12 to 24 grains)." with those numbers, is that a reading of KH or GH (i'm assuming GH but i'm not sure)?

I would say it is the GH. Most water supply companies only give the general hardness, some put it in degrees of hardness (dH) rather than ppm. You could email them to clarify if you want to make certain. Sounds like you have pretty hard water.

0 - 4 dH ... 0 - 70 ppm : very soft
4 - 8 dH ... 70 - 140 ppm : soft
8 - 12 dH ... 140 - 210 ppm : medium hard
12 - 18 dH ... 210 - 320 ppm : fairly hard
18 - 30 dH ... 320 - 530 ppm : hard
higher : liquid rock (Lake Malawi and Los Angeles, CA)
