For Ca
24 dosers per day x 6ml = 144ml per day
144 / 7days = 20.5ml average per day
You have selected to dose only two days (Fri & Sat) so 20.5 x 2 = 41ml
For Alk
24ml x 3ml = 72ml per day
72 / 7 = 10.2ml average per day
You have selected to dose only two days (Fri & Sat) so 10.2 x 2 = 20ml
I think!!!!!
