I don't know what may be giving you a problem with your magnesium testing, but I do know that magnesium is notoriously difficult to test for, and many don't bother testing for it at all. Here's a link that may help:

Good luck!

Maybe it is higher than the top end of the kit.

Is this a new tank?

mastertronics is measuring as 1100 and it is also after calibration with fm

That values seems unlikely unless salinity is very low or you added thousands of ppm of calcium over time without adding any magnesium.

Try measuring some new salt water.
