I've just plugged all my figures back in Graham's water calculator to double check my figures before brewday tomorrow. The only thing I don't have a figure for is carbonate anions, but I have everything else (total alkalinity, hardness etc. etc. - using the UU report).
Here's a printscreen of the calculator with everything plugged in. I was wondering if someone who knew their anions from their onions could just see if this looks about right? Just looking about on here my apparent gypsum additions seem a bit high.

I've only got sodium chloride (salt), calcium sulphate (gypsum) and CRS though as salts to add.
Cheers.
