This water I have used for German Pilsner and American Pilsner with success. It has no alkalinity and a calcium level of ~60 ppm. This water, Pilsner malt and 2% acid malt in the grist should yield a mash pH round 5.4.
WARNING: Boil kettle capacity (12 gal | 48 qt) exceeded. Volume required: 110.05 gal (440.19 qt). Suggest reducing initial water volume to 12 gal (48 qt) and adding 98.05 gal (392.19 qt) sparge/top-off.
WARNING: Mash tun capacity exceeded. Volume required: 55.03 gal (220.1 qt)
