This is bankrupt, no offense. Potassium augments the overall vigor of corals and that's something that you can find user support for even within the confines of this thread. Just because it wasn't used during the pioneering days of SPS systems hardly ratifies the position that it is superfluous.
The closer we get to ULN NSW water levels, the more and more we find that super low Potassium levels leads to destrimental health problems with many corals (especially SPS). This was traditionally not the case back when our tanks struggled with NO3's and phosphates, but that's all changed over the past couple years with the surging popularity of probiotic methodologies. But I digress - you run ULN for any given length of time paying no heed to your potassium (using a lower grade salt, not dosing, etc) and your SPS starts to get pale and sickly. You bring the levels up to NSW and bam, everything flourishes again.
