There is no doubt that Kalk can be used effectively to supplement Ca/Alk. A Ca Reactor can also do this on it's own, but the combination of both methods has less impact on the tank pH than either method alone. I'm right now bringing my Kalk reactor online and I'll be able to share with everyone actual affects it has on pH.

"I now have a calcium reactor up and running.
will that help with the alkalinity? or better question would be how do u control the alkalinity."

Joe Reefer has provided a good link to learning how to run your reactor. I'll just add that the reactor can be adjusted to supply more or less Ca/Alk. The only way you are going to know how much Ca/Alk your tank needs is to get Ca and Alk test kits and use them. Then you will know if your reactor is set correctly or not. WAG is no way to setup a Ca reactor!
