Help me understand Calcium

OK, I give up. I have been searching for an understandable explanation of
the relationship between Calcium level, alkalinity, pH, CO2 and whatever
else matters. I have looked at some of Craig Bingman's stuff. The guy is
brilliant. But I have no PhD in chemistry so a lot of it goes way over my
head. I understand basic chemistry (Two semesters in college with organic,
and a semester of medical school biochemistry...you'd think I would pick
it
up easily, huh) I mean GEEZ. I am not a moron, But I AM a mere mortal and
it
has been YEARS.

So, anyone know of a simple, comprehendable, explanation?? I am especially
interested in understanding (not just memorizing) the advantages and
disadvantages of kalkwasser, a calcium reactor, and the various "add a
capful every few days" products.

Any help from the experts in here?

Doug and Lois,

You do not really need to know the exact "Why" reason. It will probably
going to give yourself a big headache trying to comprehense everything. You
simply need to know your water parameter at currently and try to stay within
range. Take the link from Toni -

Look at the "Recommendation....." column. These are where your water
parameter should be or close to. Compare your current water result and see
if it close to the "Recommendation...". If if it under or over, post back to
this NG and one of us will try to answer or make some suggestion to get to
that "Recommendation....".
