You could use fusion 1 and 2 to get the alk and cal were there supposed to be and honestly depending of the amount of coral there you might not need to dose daily....I have not dosed at all...
If you dont have to much in there besides a few frags and you are regularly changing water be it weekly or bi weekly your parameters should stay pretty stable. Now of your not staying on the water changes your going to need to dose.
What are your N03 readings normally? Before the 3 water changes.
