I tried the water treatment calc with the example given on the Brupaks page but the figures for CRS come out quite different.

http://brupaks.com/water%20treatment.htm

Example given...
CaC03 is 195 p.p.m
target range of 30-50 p.p.m
to reduce the alkalinity by 160 p.p.m. CRS should be added at a rate of 0.87ml
So for 30 litres of liquor, 30 x 0.87 = 26ml of CRS.

Put these same figures in the water treatment calc and I get 49.3ml CRS?

I've just tried the old calculator...it is much easier to use than others and the results come out very similar to what Murphy and Son's recommended for different beer types after testing my water...so I'll be using this from now on.

You need to put the 195ppm in the 'alkalinity as CaCO3' box in the calculator, not in the 'Carbonate CO3' box. Put it in the Alkalinity as CaCO3 box and it calculated out at 27.0ml for 30ltrs which is similar to 26ml in Brupaks example
