My only interest is measuring my nitrates and there's quite a difference between a reading of 10 ppm with the tetra test strip, and 35 ppm with API test kit.
If you have sterile test tubes and perform tests as directed with API, why would there be such different readings?
I'm not crazy about either test chart, so what do you guys use for water chemistry???
