No, Bio Spira is nothing but cultured bacteria and does not react with any type of chemical or reagent. It will not interact at all with any test kit. It contains the exact same bacteria the tank develops on its own, over time, it just speeds up the process because you are adding the bacteria to the tank instead of waiting for them to develop. Either your kit is not working properly, there is a user error, or you do have nitrites because something has occurred to damage your biological filter, such as overfeeding or medicating the tank.
