Target Water Profile
Light colored and hoppy
Ca+2 Mg+2 Na+ Cl- SO4-2 HCO3-
75 5 10 50 150 0
Actual City Water:
Ca+2: 32, Mg+2: 15, Na+: 55, CL-:110, SO4-2: 55, HCO3-: 55-70 pH: 8.6-9
990 ppb Free & Total Chloramides/Chlorine Lab tested
After Home filtering: 20 ppb Free & Total Chlorines Lab Tested

Filtered Water Used (Primo):
Ca+2: 6, Mg+2: <1, Na+: 2, CL-:10, SO4-2: 1, HCO3-: 5-6 pH: 7.3
ND Chloramides or Chlorine

So I have decided to use 50/50 mix Primo and Home Filtered water
Ca+2: 19, Mg+2: 7, Na+: 28, CL-:60, SO4-2: 28, HCO3-: 30 pH: 8-8.15
10 ppb Free & Total Chloramides/Chlorine

and
Adding 1/2 Tablet of Campden 275 mg of Potassium Metbisulphite
to deal with the Chloramides/Chlorine
Adding 5 grams of CaSO4 (Gypsum)
to increase SO4 to Cl- Ratio (looking to ensure 3 to 1)
@ beginning of batch

and
1 Whirlfloc Tablet
@ last 5 minutes of boil
