The HI782 Checker is a simple, accurate, and cost-effective way to measure nitrate in your saltwater aquarium.

Nitrate is a by-product of the Nitrogen cycle. Excessive amounts of nitrates in a reef and fish only aquariums can promote the growth of undesirable organisms including algae and dinoflagellates which can quickly choke out filtration, lighting, and sessile organisms.
