Matter of fact, if you get the controller with the goal of running a Ca Reactor, then the day you do install one, you'll no longer have a way to test pH in your tank any longer because that probe will be dedicated to the reactor only. So you'll need a monitor after all.

OK, I'm convinced.
I just want you and Dudester to know that I spent all afternoon digging out old ham radio stuff, taking pics, and doing write-ups to sell the stuff on Ebay, just so I can help finance the pH monitor you 've convinced me I need. And maybe a Salinity monitor. (I always did like meters.) It's all your fault!
