Closest match with these salts; it can't reach Ca 60.9 mg/L vs 50, Mg 4.7 mg/L vs 27, HCO3 170.7 mg/L vs 295 exactly.
Chalk (CaCO₃) doesn't dissolve well directly in mash or sparge water without dissolved CO₂ - slurry it in carbonated water (e.g. sparkling water) before adding it, rather than mixing it into still water or sprinkling it in dry, or the calculated amount may not fully dissolve.
