Increasing Alkalinity in "Soft Water"

(That's water to the rest of us!) Beer is about 95% water, so if you want to discuss water treatment, filtering etc this is the place to do it!

Unless you are trying to avoid adding sodium ;)
Haha! Indeed :-)

Applies to crystal as well, no need to mash.

After doing separate steeps for coloured malts I think I may have hit a snag. The mash pH is bang on, but final beer pH is lowered in the addition of the steeped juices of the darker malts. I have only tested about four beers so far, so I won't nail my colours to the mast just yet. But I don't think this is going to work to have a correct final beer pH.

Use Calicum Carbonate is you dont want to add Sodium. Just slightly different maths.

Quite a bit different, and calcium carbonate is not all that soluble in plain water or indeed in the mash as I suspect that the calcium carbonate particles act as deposition sites for calcium phosphate, which is even less soluble, leaving you will still a high mash pH . . . if you add more calcium carbonate to compensate eventually you just end up with a chalky tasting beer.

I'm sure it was mentioned earlier that the best (not necessarily easiest) way to get a high alkalinity liquor using calcium carbonate required dissolving it in 'carbonic acid' under pressure
