Well, I sent a bit of a flame, and here is the response:

"I understand your frustration. Being a new customer, we had no previous tests to look at for the phosphate level…which was very high. I therefore re-tested your phosphate level myself, and the reading we got was confirmed in the second test. You may wish to take a critical look at your home kit, realizing that our test procedure is sensitive to more than one species of phosphate.
As for the calcium reading, there are distinct differences between electrochemical testing and titration-based testing. There are some excellent articles elucidating the differences and similarities that can be found on several of the online forums."

Boomer - thanks for the link, I'll try them out. Now I'm too curious not to...
