I've been having issues with SPS for a while, turning pale and dying. I have done several ICP tests and noticed smaller concentrations of lots of things I wasn't expecting to see. I have a 7 stage RODI unit and use red sea blue bucket salt, so i'm surprised to see this stuff in my water. Could part of my problem be the small amounts of Titanium, Tungsten, Zinc, Silver, Arsenic, Lead, Selenium.... I'm surprised to see any amounts of that stuff, although it appears to be small (measured in ppb). Seeing other ICP tests on here people are getting results with undetectable amounts for those elements it seems.
