Washing/Rinsing in high PH, high calcium water

[f16sunshine]

Hi all
After moving to Boulder CO last July I'm just now getting around to setting up my wet darkroom.
The water here concerns me. It is very high in calcium (550ppm). Previously my tap water was Ph7 and only 50ppm.
Can I rinse my negs and prints with it and then do a quick wash down with distiller water?
Will I need to completely filter the water?
The calcium I know will spot. Does the high PH have any other effects?
Thank you for all responses. 🙂

Here in Albuquerque, the water is about the same as your's. A final rinse/photo flo is distilled works fine. I have also at times mixed my developer with distilled water. Water spots are a pain but by being a little careful you can prevent them.
