so here is the data for the important minerals
Ca: 32
Mg: 12
Na: 61
Cl: 75
SO4: 58
CaCO3: 86
the disinfectant residuals are as follows (in PPB)
Bromate 8
Chloramines (G) 2.1
haloacetic acids 4
total trihalomethanes 22

I am going to start doing all grain, how well will this water do? I am assuming I will need to us a campden tablet for the Chloramines but how much?

One campden tablet treats 20 gallons of water; I prep 10 gallons of water for a 5 gallon batch with 1/2 tablet, crushed between two spoons and stirred into the water while it's heating.
