Kalkwasser maintains Calcium (CA). It is Calcium Hydroxide (not that this matters). Coraline needs CA to grow, so yes it will grow Coraline. When CA is right and Alk is maintianed (Kalk does both), pH will be stable too. All great for growth of coral and coraline.
BUT!
On a 10 gallon tank Kalk is very difficult. TRUST ME. I use it as one of two additives for my tank (Kalka and Iodine). You need to drip it VERY slowly to keep the CA in solution if not you will get a snow storm of CA which will not help the Corals.
I would use a CA Chloride solution like Kent Calcium Supplement (Yellow Bottle) or probably the Sea Chem product Broomer mentioned. I don't know if it is a CA Chloride sup or not. These will take far more addition to preciptate the CA in your tank (a Good thing).
You will need to maintian Water changes though. CA Chloride, if added without water changes dne (ever), will throw the Chloride to sodium balance off. This is because the corals only uise the CA and not the chloride.

You need a drip apparatus for kalkwaseer, or you'll kill everything when your ph exceeds 10. Therefore it is unsightly (A DRIP BOTTLE). Someone needs to make a good "sightly" way to dose, IMO.
If anyu one knows of a small easy kalkwasse/lime apparatus, let me know, please.
