I use beer smith for all my brewing calculations and am just getting into water profile and salt additions. i brew 15 gal batches, i use my well water and got a ward labs analysis. i brew with a herms 3v system. my hlt i fill to about 22gal to cover my coil plus some so i have extra hot water for cleaning up. i dont have exact numbers here with me but ill try to give as much info as possible. ballpark my next batch calls for 12gal water in the mash and sparge is 14gal. when setting my water addition should i set it to 12gal and add all my salts to the mash, do i set it 26 gal and add all my salts to the mash or split it with my mash and hlt, and if i split it should i then set my water addition to 36gal? trying to get my calculations nailed down so i know how much acid malt to add and this will be my first batch making salt additions and dont want to screw up 15gal of beer (that is already good without the salts). any suggestions and input will be appreciated.
