Drewster,
Not an expert at dosing Kalkwater but here is a link to some pretty good articles.
Go to
http://saltaquarium.about.com/pets/s...rium/mbody.htm
then click on aquarium care
then calcium
then kalkwater / limewater
you'll find a ton of info that I hope helps you with your new dosing pump !
Pay close attention to procedures for mixing, and adding kalk to tank, it is great stuff if added properly, but can have a dramatic affect on your pH of added to quickly. Also check up on alkalinity. It seems like calcium / alkalinity go hand in hand. Good luck man !
