CA Reactor or Dosing

[lastlight]

Someone on RC compared the costs between the two and I believe generally speaking once you're over the 180g mark a reactor is cheaper. I dose on a 400g anyways and love the complete control I have. I have much more faith in a peristaltic doser than I do pressurized gas and needle valves/solenoids etc.

I use Reef Crystals which is quite high in Calcium and as a result I dose less Calcium than Alkalinity. A balanced addition of the two (which from what I understand is what reactors do) would create an imbalance in this case.
