ICP shows Phosphorus at 10.6ppm. My hanna Phosphorus shows between 5 and 10 ppb consistently equating to .02 and .03 phosphate. No way can my Phosphorus be accurate. Am I missing something? Also is it normal for the RODI water to not be tested for silicon. That was my whole reason I did the test to see if silicates are making it through my rodi because when I use a certain brand of di resin I get diatom algae vs spectrapure silicabister I get no diatoms
