Treating My Water for a Stout

[BrookdaleBrew]

I'm pretty ignorant to water treatment. I've never done anything to my tap water other than let it sit overnight to get rid of chlorine. Our water is pretty soft (30ppm) which I understand is perfect for hoppy beers but is less than ideal for maltier beers.

I've got 2 stouts coming up that I'd like to brew and I'm just curious what I need to do to my water to make it harder. Obviously I know I can buy minerals to add to it, but what do I need to look for at the LHBS and how much do I need to add to my 30ppm water to get it to the ideal hardness?

Any help would be greatly appreciated. Thanks!
