The API Nitrate (NO₃) Test Kit gives fast, accurate readings of nitrate levels from 0–160 ppm to help prevent invisible water problems that harm fish. Nitrate build up in aquariums is often an indicator of declining water quality. High levels of nitrate are frequently associated with poor fish health, algae growth and a build up of organic pollutants.
Regular testing helps avoid organic waste buildup, poor water quality, and algae blooms, keeping freshwater and saltwater aquariums healthy and stable. This kit includes liquid reagents, a capped test tube, and a colour chart for easy weekly monitoring of nitrate produced by the biological filter.
