Gypsum vs DLS

[dedken]

Brewing tomorrow and I have run out of DLS. Am I to presume that Gypsum (being calcium sulphate) can be used in the same way i.e. a portion in the mash and the rest in the boil? And should I adjust my calculation in some way to account for there being no sodium or magnesium in the gypsum?

I will be using the 'brupaks'/nigel porter (spreadsheet from CBA website) water treatment method....

Bit late now perhaps, but you should have given me a shout, always happy to help.

Finally getting a brew on tomorrow
