I haven't got to the point where im testing my water yet but I want to. What kind of tests or kits are you guys using? It seems like the kits are pretty pricy.
Try calling your water supplier, unless of course you have well water. Then Ward as above.
I spoke with Mitch Steele at the NHC in Philly and he said that he shoots for 160 Calcium in his IPAs and doesn't care about sulfate at all.
Just another variable. Personally I shoot for both. ~300 Sulfate and ~160 Calcium.
