Nitrites

What are nitrites?

Nitrites are a form of Nitrogen in a specific form during the nitrogen life-cycle. Nitrogen compounds dissolved in water are an important class of plant nutrients. Nitrite is a nitrogen waste product in the biological filtration process. In a healthy biological cycle, bacteria convert the nitrite into nitrate, which is relatively non-toxic to fish at certain levels.

Aquatic plants, such as those found in this pond, play an important role in the cycling of nitrogen, including nitrates.

Why are nitrites important for water quality testing?

Excess levels in water can not only be toxic to fish, but humans as well!

What does a nitrites measurement mean?

  • Levels over 1 mg/L are considered dangerous
  • It is natural to have some in water
  • High levels could indicate runoff from fertilizers used in agriculture
  • Ratio is dependent on dissolved oxygen
  • High levels causes extra plant growth, which then chokes out fish (due to decreasing oxygen)

Water Rangers Protocol

We do not currently include a test for this in our kit. However, we strongly recommend the nitrites test provided by TapScore. TapScore makes the laboratory testing process easily, handing everything from bottles to labs.
