This is first time adjusting my water so of course I'm trying to get things right the first time although I know it will take some trial and error. I think I am going to take some partial advice and cut back on the Mg to 18ppm. Which in turn brings my SO4 to 253ppm. So my new adjusted water profile is:
Ca=112, Mg=18, Na=46, Cl=77, SO4=253.
Martin, I see Randy Mosher's profile for Pale Ales has a CaCO3 of 57. My CaCO3 is -42 and my Residual Alkalinity is -133. Do you think these numbers are ok for an IPA or do they need to be adjusted? Thanks for the help, this waters stuff is hard to get a grasp of!
