Nitrate is one of the most important aquatic plant nutrients and thus ought to be present in the water in sufficient levels at all times. Standard nitrate tests for aquaristic purposes often have a very short useful life or are quite imprecise. The Visocolor ECO tests by Macherey-Nagel are colorimetric and unite a high precision with a long useful life. They are excellent for exact determination of the nitrate levels in an aquarium.

Nitrate is reduced to nitrite with an inorganic reduction agent. With the nitrite, an aromatic amin is diazotized, which is afterwards coupled to form an azoic dye.
