Great video Rob for those just starting to use this kit. What I have trouble with is trying to read the various
Nitrate tests on the market. I have ones from Red Sea, Sea Chem, and Salifert of course. They all read differently. The
nitrate tests that have you determine many different shades of pink are frustrating to read.
Why is
nitrate such a hard thing to test for and does anyone prefer one kit over another?
