How to Make RO Water Mineral Rich: Getting the Result That Feels Like Spring Water

Not flat, not sharp, not thin.
Here is how to get there.
The Numbers Behind Good-Tasting Water
In practice, it describes water with enough dissolved calcium and magnesium to deliver the body, mouthfeel, and mild sweetness associated with natural spring water.
Above  best ways to remineralize ro water at home , the water starts to feel heavy and can leave a residue on glassware.
The sweet spot for making RO water mineral rich for drinking is 80 to 150 ppm TDS with a calcium to magnesium ratio of 2:1 or 3:1.
Methods That Get You There
A cartridge rated to deliver 80 to 150 ppm output from near-zero RO input produces water in the mineral-rich range without any manual calibration.
mineralizing water -off is consistency: the result depends on how reliably the drops are dosed.
Blending with high-mineral spring water can produce a mineral-rich result but requires finding a spring water brand with high enough calcium and magnesium to push the blend into the target range.
What to Notice When It Is Right
The body is heavier, the finish is cleaner, and the slight sharpness of acidic low-TDS water is gone.
A pH reading between 6.8 and 7.5 confirms the buffering effect of the minerals has raised the pH toward neutral.
Cold water in the 4 to 8 degree Celsius range carries the mineral character more cleanly than room temperature water.
Keeping  minerals to add to ro water  Over Time
A reading dropping toward 50 ppm or below is a signal to replace the cartridge, adjust the dose, or re-examine the blend ratio.
The initial calibration takes about 30 minutes.
