What type of salt are you using. Could it be your salt is causeing your water to run low and the Reactor can't raise it?

I've been running Kent and now Ocean Pure and haven't ever thought I needed to upgrade my CA Reactor

I use instant ocean but I bring the calcium and Mg up at least 24hrs before a water change. My other 2 tanks don't have any problems and my 20g uses water changes alone for its cal and alk.
