Do I need to switch salt?

This topic comes up pretty often and you will get recommendations for just about every salt out there but it usually seems the majority just use IO and add suppliments to bring the calcium & alk to the requirements of the individuals tank (probably the best way anyway). If you have a lot of calcium hungary corals probably no salt would be able to keep up and you would have to suppliment anyway so there would be no point in paying the long dollar for a "premium" salt mix.
