JR, How did you choose to run your Calcium reactor? Are you regulating the pH of the reactor with the AC and if so what do you have the pH set at?
I am still up in the air on my setup. I did not control it before and relied solely on bubble rate with my GEO, but one time that small valve they have on the output got partially clogged, made mush of the large ARM media and just averted a major disaster since the tank pH had only dropped to 7.9 after a few hours of the event.
