Well what works is different for everyone (so all of the answers above are correct, because that is what probably worked for them and that is there own opinion), and I know it isn't a straight forward answer but it depends on what works for you. People would know if they need to dose or not if they just checked there water levels regularly. You SHOULD be able to not need to dose if you do regular water changes because that replenishes your elements. But this also depends on how much of a water change you do and how often. Your calcium and magnesium consumption depends on what corals you keep in your tank and how "stocked" your tank is. Now if you have a "fully stocked" tank then your calcium will be used up more quickly but if in your tank you only have one coral, I mean it can only use up your calcium so quickly. It also depends on the salt brand you use. There are a different amount of traces in each of them, hence the different brands. I'm not saying "Don't Dose", it's just what works for you with how often you do water changes, how many corals you keep, and your salt brand. If you do decide that you need to dose, that's fine, just keep an eye on the levels because too much dosing can be toxic. You just need to find a balance for your aquarium, that’s the challenge. What works for one person may not work for you.
