This recipe requires a low level of minerals. Resources are stating mostly Calcium and Chloride but keeping both low. Calcium around 30ppm, and Chloride 30-50. Suggestion to start with the city water and cut straight in half with distilled water. Add enough chloride to get the minerals around these levels. According to one person they cut it below 50ppm for Chloride.

"I’ve never been a proponent of messing with brewing water needlessly, but for Bohemian Pilsener I make an exception. Many commercial breweries typically use water with a low mineral content and it makes a significant difference.
You can make a fine example of the style with most water, but low carbonate water helps match the character of the classic examples. You can build your water from scratch, but if your water has moderate alkalinity and you just want to get in the ballpark, try mixing your filtered tap water 50/50 with reverse osmosis or deionized water. If you have highly alkaline water, use a 25/75 mix of tap to reverse osmosis or deionized water. It is important not to use all reverse osmosis or deionized water with no mineral additions, as it lacks the buffering capacity and necessary minerals for all-grain brewing and for ideal fermentation."

Notes

Mash for 90 minutes instead of 60 at 152°F (67°C),

Cool wort to 50 degrees before pitching yeast

Ferment at a nice, cool 52°F (11°C) for 7–10 days, and when activity starts to slow, increase the temperature to about 65°F (18°C) to help clean up diacetyl. After about 14 days in the fermentor, you should be good to go. Crash to help clear the beer further, and then bottle it up and carbonate to a brisk 2.5 volumes of CO2.

When making lagers, I like to get the wort down to 44 °F (7 °C), oxygenate and then pitch the yeast. I let the beer slowly warm over the first 36 hours to 50 °F (10 °C) and then I hold this temperature for the remainder of fermentation. This results in a clean lager, with very little diacetyl.
