Tropic Marin Nitrite and Nitrate Test Kit

Product details

Tropic Marin Nitrite and Nitrate Test Kit (28360) is a water testing kit for aquariums that measures two key nitrogen compounds: nitrite (NO2–) and nitrate (NO3–). In aquariums, these ions are connected to the nitrification process, where ammonia breakdown is followed by nitrite conversion to nitrate. Using this kit helps you check whether your biological filtration is processing waste effectively and whether nitrogen levels are staying in a safer range for aquarium inhabitants. Nitrite is generally considered highly poisonous to many freshwater species, while elevated nitrate can contribute to problems such as unwanted algae growth and can inhibit the growth of more sensitive corals in marine systems. Regular testing lets you spot rising nitrite or nitrate before conditions become stressful, and it can also highlight unusually low nitrate levels in some situations.

Features:

• Tests nitrite (NO2–) and nitrate (NO3–), two common indicators of nitrogen processing in the aquarium
• Uses a finely-tuned color chart with defined ranges to help determine current concentrations
• Supports routine monitoring to help reduce the risk of nitrite toxicity and nitrate-driven algae issues
• Useful for both freshwater and saltwater setups where nitrogen balance matters
• Provides up to 50 tests, helping you keep track of water quality over time

Specifications:

• NO2 measurement range: 0 – 2 ppm
• NO3 measurement range: 0.5 – 50 ppm
• NO2 accuracy: 0.02 ppm
• NO3 accuracy: 0.5 ppm
• Test count: Up to 50 tests
