Understanding Calcium Hardness

Calcium hardness is best monitored with a dropcount titration, as test strips can only measure total hardness. In addition, whereas test strips for total hardness have just four or five color blocks to cover a tremendously wide range—from 0 to 1,000 parts per million (ppm) with color blocks for 0, 100, 250, 500, 1,000, for instance—a drop test will allow .
