yeah, I am going to join the crowd that has a few questions about the water report.
pH 7.6
Total Dissolved Solids (TDS) Est, ppm 493
Electrical Conductivity, mmho/cm 0.82
Cations / Anions, me/L 10.4 / 10.1
ppm
Sodium, Na 29
Potassium, K 6
Calcium, Ca 107
Magnesium, Mg 44
Total Hardness, CaCO3 451
Nitrate, NO3-N < 0.1 (SAFE)
Sulfate, SO4-S 11
Chloride, Cl 3
Carbonate, CO3 < 1
Bicarbonate, HCO3 570
Total Alkalinity, CaCO3 467
Total Phosphorus, P 1.48
Total Iron, Fe 0.04
I am just looking to lower my total alkalinity. My thoughts were to treat all my brewing water with phosphoric acid to a pH of 5.5. According to Bru'n water, it will take about 41 ml of phosphoric acid to lower the pH to my desired range. Does this approach sound good, and also, is my Mg high enough where I would need to do something to lower it?
I plan to add in sulfate and chloride on occasion using gypsum and calcium chloride depending on style. Can I use that also to some effect in precipitating out some of the Alkalinity?
