Hi, Reid I have checked the dw in production at 5 hours and had approximately 10 - 12 ppm. (This was at 65 degrees room temp and dw that tested .5 to begin with.) Alot depends on temperature and quality of water. This process uses room temperature dw with no heating during the process. It is best to check the CS with the Hanna PWT meter so you know where you are regarding ppm. The above is an approximate idea of what you couod expect.
