Try using a cool white fluorescent tube for checking. Warm colored bulbs make the NO3 kit impossible to read, but yeah sunlight is easiest. When the Salifert kit is used up, try the Red Sea Pro nitrate kit - it has a second vial that you match the colors to each other. I find it easier to read than Salifert when NO3 is less than 10 ppm.
