Hi, I'm looking at water profiles. I found this site online and fed in the water profiles from my local councils website. It came up a red warning sign for the Calcium saying:
Harmful. Do not brew at these levels.
However, I've just brewed my first three beers (1 gallon each) using it, although I did happen to filter the tap water beforehand through an ordinary water drinking filter first.
I then looked up the Ward labs water testing site to see what they might test for, and copied those mean average figures from the councils site.
Sodium - 20mg/l
Calcium - 284ppm
Magnesium - 2.9mg/l
Potassium - couldn't find
Carbonate - Total organic carbon as C was 0.929mg/l
Bicarbonate - couldn't find
Chloride - 28.6mg/l
Iron - 5.6μg/l (corrected)
Sulfate - 37mg/l
Nitrate - 29.4mg/l
Electrical conductivity - 565μS/cm
PH - couldn't found but average 6.5 - 9.5 given
Hardness (total) as CaCO3 - 284mg/l
Alkalinity as CaCO3 - 221mg/l
Residual chlorine - 0.48mg/l
Fluoride as F - 0.11mg/l
Might these first three beers be already ruined or did I accidentally save them by the filtering?
(Besides the fact the demis have not been in the darkness because I hadn't realised to do so).
