I live in Land o lakes Florida and just got my water report. I've been brewing extract and then biab for a few years. The wife bought me a robobrew and I did a haze craze neipa with it. I used ro water and added 1tsp gypsum, 2 tsp calcium chloride and 5 tsp of 5.2 ph stabilizer. That was before reading up on brewing water. I sent for my water report and this is the result. Ph 8.1 TDS 301 Sodium, Na 43 Potassium 2 Calcium 66.6 Magnesium 6 Total hardness, CaCO3 193 Nitrate, NO3-N 0.3 Sulfate, SO4-S 21 Chloride 31 Carbonate CO3 <1.0 not detected Bicarbonate, HCO3 202 Total Alkalinity, CaCO3 168 Fluoride 0.34 Iron <0.01 not detected I have read about the conversions that need to be done with some of the numbers. When I put this into the water calculator I use 9 gallons because that will be my total water treated including the sparge which I will use to bring me to pre boil volume. I am looking for advice on what to add so I can have a list specific amount of things to add for whatever style I'm going to brew. What I would like to do is run a potable water hose from my tap through a charcoal filter and use just that. On a side note, how long would a Carboy of ro water stay good in 80 degree garage if I put foil over the top?
