Are the Nitrite and Nitrate readings measured for a saltwater aquarium expressed as Nitrogen (N) or are Nitrites supposed to be expressed as Nitrite (NO3) and Nitrate expressed as Nitrate (NO2)?
 
two different tests, and they read as no2 and no3

and while no2 should always be zero, the no3 reading carries a different significance in relation to how the tank is set up
