Ok, brewing an APA this weekend (Zombie Dust clone), and want to make sure I have decent water to start with before I start heating my HTL. For the record, I have been brewing all grain batches of red ales, IPAs and IIPAs for months with this water and have no reason to think, as of yet, that I will have a problem with a different style.

I have a water softener in my house, but I usually bypass it for brew day just because I have heard other brewers in my area use this water straight from the tap with good success.
I am not opposed to adding some softened water or store bought water to my mash or sparge water.
Here is the grain bill:
11 gallon batch, 12.8 gallons pre-boil volume
22 lbs 12.0 oz Canadian 2-Row Malt (1.9 SRM) Grain 1 82.5 %
2 lbs Munich 10L Malt (10.0 SRM) Grain 2 7.0 %
1 lb Caramalt (12.0 SRM) Grain 3 3.5 %
1 lb Caramel Malt 60L (60.0 SRM) Grain 4 3.5 %
1 lb Melanoidin Malt (26.5 SRM) Grain 5 3.5 %
Does anyone have any suggestions on what additions/water treatments I should consider to change pH or mineral content?
