Testing would be the easiest way to tell , but it's not just sps that use up Alk and calcium other animals like coralline , fish , urchins , snails lps and even soft corals all use there share
It comes down to how much all these animals use as a whole , salt can often be enough but just the same it may not.
Some salts contain more or better chemicals while others have less.
Coralline alone can often suck up .5 dkh or as much as 2 dkh in some systems.
The best way to manage is to test and keep a log book , you never know if things could be better
