Help with Water

[Texas Ale Works]

Here is my water report.
And here is the Beer - http://www.brewersfriend.com/homebrew/r ... /193451/-1

How should I target this to get the malt to come forward,
And to get the mash PH in range?

I would like to only work with the Mash water if possible.

Thanks

With the dark crystal and roasted malt your mash pH should get in the 5.2-5.6 range. Adding a few grams of calcium chloride with help lower a pH a bit more and will enhance the malt. I don't usually add acid to the mash when brewing darker beers.
