Gypsum Question

[ChefMichael01]

I have very soft water in NYC and wanted to see what my large gypsum adjustment will do to my water profile. According to palmer's calculations, I need to add 6 grams of gypsum to get my Ca level to around 125ppm for a pale ale with 3.3 gal of mash water (my tap water has 5ppm of Ca and 5ppm of sulfate). I know gypsum adds a lot of sulfate to the water profile, but am confused by Palmer's calcs. If someone could confirm my calculations and let me know if this will produce too much sulfate I'd appreciate it.

thanks.

I punched your numbers into beersmith and got
Ca 117.7
Sulfate 274.1
doesn't sound very tasty.
might be better off balancing it with gypsum and calcium chloride

Nothing wrong with that if you're planning on brewing an IPA or pale ale. Look at Tasty's recipes, all his american style beers are 350 ppm sulfate, 110 ppm Ca.
