ive try'd to look at this a few times but never made an sense out of it all, so i hope some of you can help.
i've entered the figures in to the water treatment calculator here on jims site http://www.jimsbeerkit.co.uk/water/water.html
i've used the figures from my area provide here http://www.ywonline.co.uk/web/WQZ.nsf/0 ... %20WSZ.pdf
and here

heres a picture of the figures entered

questions
how do i find out the Carbonate co3, the Alkalinity, and Hardness
and whats this Carbonate Reduction Method - is this what you do or add to the water to reduce the carbonate, how is this normally done ?
how do you work out the Sulpahate Chloride Ratio ? is it needed?
when i enter the figures the calculater shows a warning as below

have i entered the figures wrong ?, whats it telling me, could it be becasue i havent entered all the figures ? is it a problem ?
the water report doen't show the ppm of most of the elements.
how can i find these, calcium, bicarbonate, sulfate, chloride, sodium, magnesium, as most calculators i've seen want this information.
thanks to all
