The API Nitrate Test Kit helps you monitor nitrate levels in your aquarium. Nitrate builds up over time from fish waste and decaying organic matter. High levels are a sign of declining water quality and can fuel algae growth, while keeping nitrate low helps support healthier fish and invertebrates.

This kit reads nitrate from 0 to 160 ppm and suits both freshwater and saltwater aquariums. Regular testing shows you when it’s time for a water change, and with 90 tests per kit, it’s an economical way to keep on top of water quality.
