I just bought a new 5 stage RO/DI unit from BRS, and after running it for a couple hours (65 PSI, 0 TDS reading) tested the phosphates. I used the digital Hanna Checker, which is supposed to be accurate to .01PPM with +/- 0.04 variability. Here are my results:
RO/DI water: 0.10PPM
Newly mixed water with Tunze Reef Salt: 0.14PPM
Tank water: 0.15PPM
Tap water with no reagent: 0.01PPM
I'm disappointed with this reading - do you think my tester is off, or are the phosphates really that high? I ran out of reagent, so was unable to test my tap water for comparison...
