alkalinity versus carbonate versus temporary versus KH versus German (hardness)

Well, I look at my Red Sea HARDNESS test kit "For the Determination of
Total (GH) & Temporary (KH) Hardness. 
On the back under Instructions GH: it says that GH means German Hardness
and is measured in degrees (or drops).

Then under Instructions KH: it says that the quantity of drops used
equals the carbonate hardness. (in German Hardness). Wait I'm confused!
It was all so clear when soapy George clarified it... I think I am
getting some kind of calcium precipitate!! Is the calcium permanent or
temporary? This is just getting too Hard to understand...

I don't think we can fault the Germans for the labelling because on the
bottom it says "MADE IN ISRAEL". I recall that alkalinity-George wrote
that this business of temporary hardness began or ended around the
Second World War. Coincidence???

And just to cover ALL the bases, they also include instructions in
French, German, Italian, Spanish, Swedish/Finnish(?) and american (for
the foreigners).

I guess I am now Finnish. ;-)
