Hi, I haven't tested Nitrite since my tank cycled but someone suggested I should try it out.
Since the Mastertronic has a Nitrate Compensation feature where it tests for both Nitrite and Nitrate to provide a more accurate result I decided to give it a try.
The results were odd to me.
When I activated that feature I got 0.037 ppm Nitrite and 3.46 ppm Nitrate.
When I tested for Nitrate only (as I usually do), my result was 7.42ppm
My Hanna Nitrate HR checker reported 11.1 ppm but that is common, Mastertronic has historically reported lower than Hanna in my case.
Does the relation between nitrite and nitrate make any sense to you?
I don't understand how Nitrite and Nitrate interact when the Hanna checker tests for it but I kind of expected the values to add up somehow.
I hope @Randy Holmes-Farley can chime in and share if that makes sense chemically. Maybe I'm asking too much from hobby grade test kits?
