Here is some information that may help. The MSDN shows the reagent is somewhat harmless.

Three pages and it still doesnt say what the regent is, other than "white powder"?

It also states "Do not discharge into the drains/surface waters/groundwater’s."

How many of us are dumping it down the drain? I know I do.

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.
