I'll be the first to agree that calcium and magnesium levels are typically low on RC and IO salt so you do need to use calcium, alk, and Mg additives, but the salt tests good for everything else. Your results are in line with what most people get. I think buckets or test method used in the article has something different happening. There was a note about calcium and free calcium in the article. Maybe their test method does a better job of picking up the calcium than our test kits or maybe their sample wasn't a representative sample of what most people get. That's why I think they need to go more tests if they want their results to be deemed reliable.
