Eric briefly talks about calcium hardness, and explains how it can rise and fall. In short, if calcium increases, it's coming from somewhere. If calcium decreases, it's going somewhere. Two-breath summary at the end.
00:00 - Intro
01:29 - The amount of calcium carbonate is calcium hardness. How saturated that calcium carbonate is is measured using the LSI.
02:45 - If calcium rises, it's coming from somewhere. If calcium falls, it's going somewhere.
03:21 - What increases calcium hardness?
05:03 - What reduces calcium hardness?
07:02 - Evaporation and accumulation
08:53 - If the calcium seems to move much more than it should, it's probably a faulty test
10:16 - Two-breath recap. Thanks for listening!
