Hi Brad, thanks, that is basically what I'm trying as I try to dial in the two reactors together. (Ie. using the two-parts until I get Ca=390 and Alk=3.0, then let the reactors try to maintain after that point.) It's just that over time, Ca will will fall, and Alk will rise. Which wasn't quite was I was expecting, I was expecting both values to rise (or drop) together. If I run the kalk by itself both values will drop. If I run the Ca by itself I should theoretically be able to retune to the system's draw rates but I was hoping to add kalk to the mix because it helps to precipitate out phosphate (or so I thought).
I dunno maybe I'll just give up on the kalk for now. It's not like I have any SPS left, so the draw should be fairly low anyhow, but I was hoping to maintain the levels for the benefit of the other things I have left (clams and LPS).
