Lindoya Joia is a still water from Brazil. Sodium-bicarbonate type, low mineralization. Label prints bicarbonate as 'NaHCO3'; used as HCO3, which is what closes the ion balance.

| Baking soda (NaHCO₃) | 3.74 g | 3.95 g |
The common salts reproduce every ion within 10%.
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.
