My magnesium dosing is 100ml a day (Using BRS Pharma Magnesium Mix). This seem high, based on my 25 ml of the Calcium solution. What should I be looking into?

The tank is testing 1425 magn, 450 calcium.What are the values? Have you tested your salt mix?
So, the reference is supposed to be 1310? And when you test with the kit it shows 1500?The tank is testing 1425 magn, 450 calcium.
I have not tested the salt mix (using Instant Ocean).
I used the reference solution and the bottle shows 1310 but the test showed 1500.

I suspect that this is problem with the way most Magnesium tests are devised-I believe reference solution Mg level is like stated and I do believe test kit is probably OK. I had similar problems testing Mg, sometimes had to check twice to get result I thought to be more probable. I hope you have noticed that you suppose to add 5 drops of reagent A and 3 drops of reagent B.The tank is testing 1425 magn, 450 calcium.

Do you have any mangrove in your sump?

Yep - LFS testing is next on my list.I suspect that this is problem with the way most Magnesium tests are devised-I believe reference solution Mg level is like stated and I do believe test kit is probably OK.

As Randy said-your Magnesium consumption is a fraction of Ca/Alk, so I would dose magnesium based on those and possibly skip Mg testing. You could also test your water at LFS as after your heavy Mg dosing it might be bit off the charts now.
There is nothing wrong with 1350.I changed to a Salifert test kit...it is showing 1340. I dosed with Seachem IONS Magnesium (100 ml) and still testing 1350.
