I used to have a Red Sea nitrite test (which came in their Deluxe Fresh Lab kit) but recently finished it. I got an Aquarium Pharmaceuticals (Doc Wellfish) nitrite test the other day.
my question is, why does the Red Sea one register much lower concentrations of nitrite (the first reading is 0.05 ppm, next 0.1 ppm, etc.) while the API test goes from 0 to 0.25 with nothing in between? the instructions claim that the API test is up to 3.3 times more sensitive than other tests. what gives?
should i be worried, because my oto's used to start breathing heavily if nitrite registered as low as 0.1?
