Okay, I'm just getting into looking at water. Low efficiency brought me here.
So, the first thing I did is order a brew test on my water from Wards - I'll post my results below, but that is not what my question is about.
Putting the results into beersmith, and then asking it to calculate what I need to do to make my water be similar to that say in Denver, CO, I get a set of additions to make - including epsom salt, chalk, etc.
Is this just to get my levels similar to Denver, CO - which has a ph around 7-8 - and then I need to also make the recommendations in the primer (Baseline: Add 1 tsp of calcium chloride dihydrate (what your LHBS sells) to each 5 gallons of water treated. Add 2% sauermalz to the grist.) to get the ph down?
So...tweak my local RO water to model a region and then also treat it as the primer notes to get the ph down?
If this is the case - I think my first step would really be to just apply the primer to my RO source to get this process working first - would you agree?
Okay - thanks for the great section, and for any help.
Here are my RO water source results from Ward Laboratories:

Potassium, K < 1 ppm
Calcium, Ca 2 ppm
Magnesium, Mg < 1 ppm
Total Hardness, CaCO3 5 ppm
Nitrate, NO3-N 0.1 (SAFE) ppm
Sulfate, SO4-S < 1 ppm
Chloride, Cl < 1 ppm
Carbonate, CO3 < 1 ppm
Bicarbonate, HCO3 6 ppm
Total Alkalinity, CaCO3 5 ppm
Total Phosphorus, P 0.26 ppm
Total Iron, Fe < 0.01 ppm
"<" - Not Detected / Below Detection Limit
