Is it possible to have 1520 ppm Mg WITHOUT dosing Mg?

I am using the Red Sea Mg Test kit and it currently showed me 1520 ppm.

I don't dose for Mg and thought that was a little odd to be that high. Am I just botching the last part of the test and adding the Titration too quickly?

What all do you dose? What is your salinity at?

Check your salt mix .I use HW Marine Reefer salt which is higher on Mg and I've almost always had very high Mg (1500) until my coralline started taking off. Running a softie tank so uptake is always low from corals.

I use reef crystals when I have to make my own. Lately they had some Nutri-seawater at the LFS which I have been using for the past 2 weeks.

Its possible to have higher MG, but, it will now harm anything at that level. I was using HW Marine Reefer mix and constantly ran Mg at 1480. I actually like to keep my Mg at 1500+.

It is not unusual to have high mg in reef crystals.
