I brew on a EHERMS. My HLT is a 20gal blichmann with a SS coil. I need to fill it up with 13 gal of water to cover the coil. My water PH is 8.1:(. I cut my mash with RO and add salts. Question is is there any other way I can bring my HLT/sparge water down to a good PH level without cutting it with RO. My water profile is 66ca, 20mg, 27na, 18cl, 36 sulfate, 262 bicarbonate. I have added latic attempting to decrease the PH but soon learned that the buffeting of my hard water prevented my PH from changing
