Recently I started noticing a drift in the ICP po4 measuments compared to the actual po4 that I measure using Hannan home kit.
Not sure why, but there is a drift for sure..

I have the same issue the RODI seems to be compared to seawater setting.. still unresolvedI sent in a test last week and it was received on 12/17 and my results have been posted (not sure exactly when because right now is the first time i checked) so seems like their server issues might be fixed BUT my tank results have two negative values and RODI has 9 negative values. I'm not a chemist but I'm pretty sure you cant have negative elements in your water.
