Thanks for the read. I contacted Fritz and they replaced the box of salt. I'll test the parameters on my next WC.
Other than the dKH been in the low end, this salt will be on top of my list for various reasons. First off, they are local to DFW, their customer service is outstanding and the salt mixes to clear within a few minutes (10-15) and is ready to use. Fritz recommends waiting at least 12 hrs to assure all levels are stable but in a pinch this could safe a reef.
