Salifert Nitrate Test Kit The Salifert Nitrate Test Kit is a fast aquarium test kit for measuring nitrate in reef, marine and fish-only systems, with dual ranges for low and higher nitrate levels. Nitrate Testing for Reef Nutrient Control Nitrate is a key nutrient to monitor in reef aquariums because elevated levels can contribute to nuisance algae and may affect coral colour or growth. This Salifert kit provides quick results and is designed to avoid amine interference that can make nitrate appear lower than it really is. Salifert Nitrate Test Kit Features Measures nitrate from approximately 0.2 - 100 mg/L as total nitrate. Low range: 0.2 - 10 mg/L as nitrate. Medium range: 2 - 100 mg/L as nitrate. Total testing time is less than 3 minutes. Designed to avoid amine interference for more reliable nitrate readings. Sufficient for approximately 50 tests. Useful for reef tanks, fish-only systems, nutrient control and algae troubleshooting. Nutrient Management Notes Use nitrate results alongside phosphate testing, feeding habits, water-change schedule and filtration performance. Avoid making large nutrient changes based on one test result; track trends over time for more controlled aquarium management. Directions Follow the current instructions included with the kit. Use clean test vials and scoops, read the result under consistent lighting and clean the test vial and scoop after use. Store the kit in a dry place between tests.
