Not long ago I asked for help on how to reduce my Total Alkalinity as Calcium Carbonate. My Total Alkalinity CaCO3 living in San Antonio, was around 235, which is way too high for many of the light beers that I desire to brew. Two people were quick to help me out and I just wanted to post a follow up on how my water profile before and after turned out.
I followed the instructions in this link Alkalinity reduction with slaked lime - German brewing and more and found it to be really easy to figure out how much lime to use in order to take out the CaCO3. I sent a before and after Wards Lab just to be sure that I wasn't going to change my water to something dangerous and below are the results after following the article step by step using the included calculator.
Before Profile:
Na: 11
Mg: 16
Total Hardness, CaCO3: 183
Sulfate: 11
Cl: 16
HCO3: 220
Total Alkalinity, CaCO3: 235
After Profile:
Na: 11
Mg: 12
Total Hardness, CaCO3: 85
Sulfate: 6
Cl: 17
HCO3: 47
Total Alkalinity, CaCO3: 54
As you can see it worked! Yes, I will have to add salts, but I wanted to show what the water looks like after nothing done to it but the 24 hour Ca(OH)2 treatment. I cant wait to start brewing with this water this weekend. Thank everyone for the quick replies. If you have any questions I will definitely pay it forward by answering as best as I can. Happy brewing!
