Fiji is a still water from Fiji. Bicarbonate-dominant water with notably high silica, giving a soft, slightly sweet mouthfeel.

Mineral salts to dissolve in reverse-osmosis or distilled water, calculated by the BrewWaterSolver solver with the most common homebrew salts.
| Salt | 5 gal (18.9 L) | 20 L |
|---|---|---|
| Calcium chloride (CaCl₂) | 0.22 g | 0.23 g |
| Epsom salt (MgSO₄) | 0.08 g | 0.08 g |
| Chalk (CaCO₃) | 0.69 g | 0.73 g |
| Baking soda (NaHCO₃) | 1.11 g | 1.18 g |
Closest match with these salts; it can't reach Mg 1.4 mg/L vs 14, HCO3 90.1 mg/L vs 158.5 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.

Yaqara Valley volcanic aquifer, Viti Levu, Fiji. Updated from FIJI's 2026 US water quality report; HCO3 from total alkalinity 130 mg/L as CaCO3 (x1.22) - the report's own 'bicarbonate' row doesn't close the ion balance.
