Before you use it
Extremely hygroscopic — the crystals clump and weep in humid air, which makes weighing unreliable unless the tub is kept sealed. Same magnesium ceiling applies: stay under about 30 ppm.
Description
The chloride route to magnesium, useful when a profile needs a touch more magnesium but no extra sulfate. Reads as a subtle fullness rather than the dry snap Epsom salt gives.
