Nitrate Test Kits

[snackdaddy]

Does anyone know the best, most accurate test kits available?
From the same batch of water I used API and got a reading of 20ppm, took it to one lfs and they got less than 10ppm with a API kit I think, took it to another lfs and they used a strip and showed 0ppm. I took the advice of the first store and bought a Nutrafin kit and still out of the same batch of water I got 5ppm.
What to believe, same batch of water, 4 test, 4 different results. Any thoughts out there on this??

I have found the seachem tests to be easy to read and cost effective.

No matter what test kit you get, nitrate results are only as accurate as your adherence to the testing procedure

followed instructions to the tee, on both kits.
