Build your recipe

Start with the volume of water you're preparing, then set a target for each mineral.

Targets

Litres

Enter the ppm you want and we'll tell you how many drops.

DropperTarget ppmStrength*

* Strength = ppm added by one drop to 1 litre. Adjust to match your own droppers.

Assumes your starting water contributes 0 ppm of each component. Drop size and stock concentration can vary, so treat results as a guide. Bicarbonate is shown on its entered ppm basis, not converted to alkalinity as CaCO₃. Silica is non-ionic, so it barely registers on an EC/TDS meter and is left out of the Est. TDS figure.

Your recipe

Rounded to whole drops. Resulting ppm = drops × strength ÷ litres, so it can differ slightly from your target.
