Reef Moonshiners definitely has the evidence that it does in fact work well at getting corals to grow and color up. However, these results can be replicated with any major brands PRO version of salt, plus an Ionically-Balanced complete 2-pt balling system. I've used the Red Sea Pro /ATI essentials pro 2pt combo for years, and haven't looked back.
Can you post some pics of your corals?
