I'm getting my water tested in the near future. I have a whole house water softener system and I'll be testing one batch after I run it through that just for general knowledge. My other option for brewing is to bypass that system, however that will also bypass the filter. So my options are testing unfiltered water, buying a brita system and running it through that, and what else? Any other suggestions for making good water without a big up-front investment (not an R/O system)? Thanks.
