Phosphate kit accuracy?

Thanks WaterBear...I plan to pull a tapwater sample tomorrow & get the phosphates tested so I can compare their #'s to mine.

I had the phosphates checked on my tap water today. He came up with about 450ppb on 3 different tests. Only problem is, he was using strips from 3 different suppliers. I tried to find someone that could test it without using strips but drew a blank. Those here in town that could test it used strips.
