Could you reword your question a bit? Are you asking if it will take the place of traditional calcium/alkalinity/magnesium (plus some trace) additive systems or are you asking a different question entirely?
In the past I have used the following additive systems: Aquaforest, ATI, Triton and Red Sea. Currently using All for Reef along with some Polyp Lab additives. Corals are doing at least as well if not better than with any of the others.
