It's completey dependent on what is in your tank (corals and inverts), what you're feeding everything, how often you're doing water changes, how strong your mechanical filtration is, etc.
There is no one right answer. You could use a salt with the highest numbers, but if the tank is packed out with huge clams a d SPS colonies, chances are you'll have to dose.
