If you already keep params up by say dosing 4 cap fulls of purple up then you know roughly you use 20ml per week so you dose 20 ml spread over 7 days.
I dose anywhere from 180 to 200 ml per day of cal so I spread it out over 20x in a 12hr period, my alk and mg dosed at the same time frame but on the next 12 hr period.
So this is my dosing chart:
10am-10pm Ca 180ml
12am-8am Alk 160ml
11pm-8am Mg 170ml
And as the OP said test every 3 days to make sure everything is bang on for first week, if it is test weekly then BI weekly and so forth.....
