I've double-checked alk and ca against alternative kits (salifert and API in addition to Red Sea). I generally check alk a about twice a week, and use that as a basis to bump two part dosing. Ca I usually only test every other week or so. All my kits show Alk is right where I've been trying to keep it, between 7.5 and 8 dKH depending on time of day (highest just before lights on, lowest just before lights out). Ca seems to have crept up a little bit. About 440-460ppm, up from 420ppm two weeks ago. Base on that, it seems like Alk consumption is slightly outpacing Ca consumption for whatever reason. Since I mix from concentrate, it's possible that I just used slightly more RO/DI with the alk mix than the calcium. I've lowered Ca dosing by ~12%. I'll check it again in a few days to see if it's dropping off a bit.
The Salifert mag kit is actually brand new. Red Sea Mg titrant was running a little low, and I thought I'd try something else just for the heck of it. If I have time later today, I may take a sample down to the LFS to see if I can get them to double check it on one of their kits.
Glad I read this thread! I've read before the mollis are slightly more sensitive than some other montis when it comes to water quality. Seems like it may have served as a canary in the coal mine for me.
