Here is a thread on Reef Central which looks at the accuracy of the phosphate checker:

I would really like to know what the low limit of detection of phosphates is for the phosphate checker. Both my reef tanks read 0.00 ppm phosphate and I don't believe the phosphate level is really zero. I will set up an experiment with serial dilutions to see how low a level of phosphate is detectable by the phosphate checker.
