Direct Mineral Additions
The following calculator converts concentrations expressed as CaCO₃ back to g/L for a more traditional format. Please note: Sodium is handled as a special case where the “desired ppm” is for sodium ions – so “10 ppm” here would mean 10 mg/L sodium and 15.4 mg/L chloride.
Ion Profile Calculator
Please note Sodium measurement is for 1000 mg/L sodium.
1000 ppm Concentrate Calculator
Usage: Add 1 g of concentrate for 1 ppm of either GH or KH (as CaCO₃) in a carafe to create your brew water .
Then top up with deionised water until you reach 1000 grams on your scale. (You can of course also just top up with 500 g, but in that case you need to double each gram of concentrate = 2 ppm instead)
