Nyos Nitrate Test Kit Nyos Nitrate Test Kit is a high sensitivity seawater nitrate test kit for measuring NO3 in marine and reef aquariums. Nitrate testing helps aquarists monitor nutrient trends, evaluate filtration performance, adjust feeding or export methods, and keep reef aquariums within a stable nutrient range. Nitrate Testing for Reef Nutrient Control This Nyos REEFER nitrate kit uses highly sensitive reagents, a professionally calibrated colour chart, differentiated colour gradations, and a sliding comparator to make visual testing easier. The 1-160 mg/l range is useful for reef systems, fish-only marine aquariums, new setups, and tanks where nitrate trends need to be monitored regularly. Nyos Nitrate Test Kit Features High sensitivity seawater nitrate test kit for marine and reef aquariums. Measurement range of 1-160 mg/l or ppm NO3. Professionally calibrated colour chart for visual comparison. Differentiated colour gradations help improve readability. Precise sliding comparator supports consistent sample comparison. Reagents are made in Germany under strict batch and quality control. Designed for approximately 40 nitrate analyses. Nitrate Test Specifications Product type: Seawater nitrate test kit Parameter tested: Nitrate / NO3 Measurement range: 1-160 mg/l or ppm NO3 Number of tests: Approx. 40 Application: Marine and reef aquariums Includes comparator: Yes Test kit series: Nyos REEFER Manufacturing: Made in Germany Reef Testing Notes Nitrate should be interpreted as a trend rather than a single isolated reading. Use repeat testing to evaluate changes from feeding, stocking, water changes, refugium growth, skimmer performance, biological filtration, or nutrient reduction media. Nyos Nitrate Test Kit Video Directions for Use Rinse both measuring jars with aquarium water before use. Add the water samples as directed, then add NO3-1 and NO3-2 to the test jar according to the instructions. Shake and wait for the recommended development time, then place both jars in the comparator and read the nitrate value from the colour card while viewing from above. Rinse test equipment after use and store reagents tightly closed.
