I was unable to get any reading at all using the strips.I took a water sample to a water testing site and it showed Phosphates.But the test strips did not show phosphates.Unfortunately I can't recommend the product.

Works as expected and easy to figure out how to use. Helps us manage the phosphate levels in our hot tub.
