Had a close call yesterday with Ca dosing

[Reef Pilot]

Well, I just tested my Mg, and another surprise. It was on the low side at 1350. I expected it to be higher with all the dosing. Of course, I don't know what it was just before the over dosing. I hadn't tested Mg since Jan 13 (I keep a log), and it was at 1440 then.

So, while all this doesn't make total sense to me, my params are still within range, and corals all look fine.
