BeerSmith water

Do I have to enter the salts manually(In Tools) or BSmith will enter amounts of salts(grams) automatically to correct  my water  profile to match chosen profile?

You need to enter them.  But there are several tools on the net that can help you figure out how much you need to add.  EZ water is good as is brewers friend.

I've watched  the video on Utube explaining how to use Ez_Water calculator; it's fairly easy after a while and similar to BeerSmith. It would be nice if one could specify profile of the beer, enter your own water parameters and get calculated additions taking under consideration bitterness and maltiness you need. Thanks for fast response.
