Nitrate is the final step in the Nitrogen cycle. Excessive amounts of nitrates in saltwater aquariums facilitate the growth of undesirable organisms such as algae and dinoflagellates. The HI782 is a simple, accurate, and cost-effective way to measure nitrate from 0.0 to 75.0 ppm (as NO3–) in your saltwater aquarium.
