Salifert Nitrate Test Kit

The Salifert Nitrate Test Kit measures nitrate concentrations between 1 and 100 ppm using a reliable liquid reagent method, suitable for both freshwater and marine setups. The test requires a brief incubation period for the reagent to fully develop, rewarding patience with a clear, readable color result. At 0.5 ppm sensitivity in the low range, this kit is particularly useful for low-nutrient reef aquariums where nitrate must be kept near zero for SPS coral health. Each kit yields approximately 50 tests. Regular nitrate monitoring guides the frequency of water changes and the effectiveness of refugiums, protein skimmers, and denitrification media.
