GH Ruby Mild - any advice on water profile?

[The-Engineer-That-Brews]

Not brewed a mild before, so any advice welcome on this one will be welcome.

It's an OG 1049, and the grain bill is:

4.5kg pale malt​

150g medium crystal​

150g chocolate malt​

125g torrified wheat​

For what it's worth, my tap water is Ca 145, Na 30, HCO3 333, SO4 42, Cl 55, NO3 31; and I've got plenty of RO available :-)

Thanks in advance

I'd go fairly well mineralised, slight bias to chloride - say 150 sulphate, 200 chloride? But either boil, dilute or neutralise some of that hardness first...
