What's Kalkwasser?

[LittleParr]

As i'm just getting going in this hobby and trying to do everything right, can anyone tell me what Kalkwasser is, and should I be concerned about it? (I am assuming it has to do with water and calcium)

www.reefscapes.net/articles/breefcase/kalkwasser.html and www.algone.com/kalkwasser.htm you can read this on it it will help I use in in my two main tanks.
