I'm trying to use Beersmith to go from Washington, DC water to Burton on Trent water for a quantity of 15 gallons of starting water. I've got gypsum, epsom salt, table salt, and baking soda. I can get pretty close with 60g of Gypsum, 14g epsom salt, and 14g baking soda. That seems like way too much gypsum, though. I got a little ID Carlson jar of gypsum from a homebrew store, and the entire jar is only 54g (2oz).
I know BoT water is hard, but that seems excessive, even for 15 gallons. Can the calculation in Beersmith be right?
