Calcium (Ca) - An Essential Reef Tank Element
Also known as limewater or kalkwasser, calcium is an important and essential reef tank additive. Here is information all about calcium, how to mix and add it, measure carbonate calcium (dKH or KH) hardness levels, and more.
About Adding Limewater to Reef Tanks
From your About Guides Articles Archive, Debbie and Stan discuss what limewater (a.k.a. kalkwasser or calcium) is, how much to add, as well as how to properly prepare a solution and introduce it into reef tanks.

Calcium Measurements Explained
From the FINS Reefkeeper's FAQs, information about how calcium content (aka carbonate hardness) is measured either in ppm (parts per million) as calicum ion (Ca++) or ppm equivalent calicum carbonate (CaCO3), the relationship bewteen them, and what the acceptable calicum range should be for reef tanks.

Evaporation Make-Up Water & Kalkwasser
From Robert Metelsky's "Simplified Reef Keeping" FAQs, Robert gives an explanation of water evaporation, why it occurs and how to replace it, as well as how adding kalkwasser (calcium) to the make-up water provides a good opportunity to replenish much needed calcium in reef tanks.
