Question How do you dose ferts without measuring them first?

I'm a bit of a scientist type, so it bothers me to dose a tank without measuring and knowing how much of something I'm starting with. Do people measure their tanks for Ca, Mg, Fe, etc.? If so, are there test kits out there? If not, how do you know what and when to dose?
