You guys' dosing sounds really complicated.
I have dosers that dose 3x a day each, and I test once a week. Manually dose once a week if needed after testing, and if I have to manually dose two weeks in a row I will increase the doser by a few minutes. If something is too high I will unplug that doser to skip a dose or two.
Before I got dosers I would manually dose calcium in the morning and alkalinity at night using equal parts. Once a week I would test, and add whatever was needed to balance out. If something was too high I would skip dosing that one for the next day or two.
