Nitrates

Nutrients are essential for life to exist and continue to develop.

Nitrates are a combination of nitrogen and oxygen in an organic form.  These can be broken down and utilized by plants to a certain degree, but are harmful in large concentrations because they can increase the amount of aquatic plant growth to a level that can't be sustained in the body of water without affecting other aspects of the ecosystem.  The recommended value for nitrates is 44 parts per million (ppm).
