Not necessary. They subtly improve the quality of the beer, but you'll be fine without them. The purpose is to amend the water to be similar to the water from the brewing region in question. But, oddly enough, Pils water is very soft, so I dunno why they call for them. Usually you use them when trying to recreate Burton-On-Trent water, etc.
