I'm glad to hear you have figured out the problem.  Sometimes automation kicks our butts doesn't it?  Eep!  I look forward to hearing about the turn around!

  Phosphate - Hanna low range colorimeter
  Nitrate - American Marine Nitrate Moniter (probe)
  How are you able to detect 1ppm of phosphate? The Colorimeter isn't accurate to more than about 1ppm.
