I just put in an order with Buckeye Hydro for a premium RO system,100 GPD . Now I need to learn water chemistry . The past I have used tap water, then moved to the country with a well and softener, not good to brew with. I’m looking for a brewing program that is easy to use for RO Water additions and can give me the expected mash ph. I never bothered with ph because my beer always came out good to great . I used the test strips , but could never alter my ph to make a difference. Time to step it up a bit . I currently use Brewersfriend but it doesn’t give me an expected ph for my grain bill. Thanks for the help.
