Finally I bough RO system and I decided to learn more about water chemistry in order to create water profile for my next batch. I read Brun Water Knowledge (which is excelent) and few articles just to get some basics... I am trying to workout my new water profile with RO water using EZ Water and Bru"n Water calculators.
I dont know what am doing something wrong, but it seems that calculators give me different pH value with this water profile and grain bill:
STARTING WATER PROFILE:
Ca- 9 ppm
Mg- 3 ppm
Na- 0.2 ppm
Cl- 1 ppm
SO4- 1 ppm
HCO3- 14.6 ppm
GRAIN BILL:
Pilsner- 8 kg
Wheat- 0.5 kg
Crystal 60L- 0.8 kg
SALTS TO ADD:
CaSO4 (Gypsum)- 3g
CaCl2 (Calc. Chloride)- 6g
MgSO4 (Epsom salt)- 3g
NaHCO3 (Baking soda) Mash only- 2g
MASH pH RESULT:
EZ Water: 5.67
Bru"n Water: 5.3
Also, final sodium concentration is different, according to EZ Water it will be 9 ppm and according to Bru"n Water sodium is 18, even I didnt added baking soda to sparge water.
Any help is higly appreciate.
