I also quit testing Mg, for years it was always 1440, all of sudden it was below 1100.
I use Reef Crystals, a year or so ago I started loosing corals and found that the mixes are very low and inconsistent in Mg.
I'm back to testing each mix & they seem to be coming in around 1300 to 1350, but some mixes still show low 1200's.
