There's lots of info on this BB...I'd do a search and come back later with any questions. You'll need auto top off before you setup a kalk reactor.
I have both, used both and no longer use my kalk reactor. A Ca reactor will keep up with the Ca and Alk demand of a fully stocked tank, a kalk reactor most likely wont. The problem with a Ca reactor is they tend to lower pH levels, Kalk reactors tend to raise pH levels so they complement each other...
FWIW, I use a reverse flow Ca reactor, these tend to use less CO2 so they don't effect the tanks pH as much
