Radenska is sparkling - the salts give you its minerals; carbonate the water yourself (e.g. with a soda maker) for the fizz.
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.
