Why test for nitrate?
Nitrate analysis is important to determine the condition of mature aquariums. High concentrations of nitrate suggest an elevated level of pollution and indicate it is time for a partial water change. High levels of nitrate promote algae growth and increase fishes stress level, resulting in a reduced resistance to disease. Nitrate levels in oceans and rivers is close to zero.
