Test daily for a week, see how much it drops, input how much it drops into this calculator https://reef.diesyst.com/chemcalc/chemcalc.html. Then you start dosing said amount daily, test once or twice weekly and tweak as needed. Depending on your coral needs and consumption you might not even need to dose daily.
