On the list, but - do you have outside air to your skimmer or CO2 media? I have never noticed a pH hit from a CaRx.Speaking of content... I would love it if you would discuss the pro's and con's of 2 part (or Balling) dosing vs Calcium Reacotors.
Dosing over 250ml per day on my 187g mixed reef am seriously considering a calcium reactor but not happy about the potential pH hit.

Cost comment was just to maybe off set the initial sticker shock when pricing reactors. That always seems to startle most people but when you look at the bigger picture it changes. Like you the 15 day thing.
In either case - sounds like maybe you are ready to make that plunge
