yes your correct buddy" ammonia salifert you look from side on! and nitrite from looking down when over top of test glass !Be certain you're reading the salifert test correctly. My memory is iffy, but on Salifert Nitrate, for example, you read the test as you have pictured... looking down through the vial from above and contrasting the colors.
I believe that on the ammonia test, you are instructed to hold the vial vertically, in front of your eyes with the color chart held behind it and to interpret the colors by looking through the vial from the side.
