High-Accuracy Nitrate Testing for Reef Aquariums
The Red Sea Nitrate Pro Reef Test Kit is an advanced colourimetric test designed for accurate measurement of Nitrate (NO₃) in marine and reef aquariums.
Rather than relying on a basic colour-card comparison, Nitrate Pro uses Red Sea's comparator and colour disc system to provide precise nutrient measurements across a 0–64 ppm range.
Why Test Nitrate?
Nitrate is one of the key nutrients to monitor in a marine aquarium.
Regular testing allows you to follow nutrient trends and make informed decisions about feeding, filtration, water changes and nutrient management rather than reacting only when problems become visible.
For reef aquariums, accurate nitrate measurement is particularly useful when managing controlled nutrient levels or using nutrient-reduction systems.
High-Accuracy Comparator Testing
Nitrate Pro offers:
• Tested parameter: Nitrate (NO₃)
• Test type: Colourimetric comparator
• Range: 0–64 ppm
• Accuracy: 0.125 ppm
• Number of tests: Approximately 100
The comparator system makes the kit particularly useful where small differences in nitrate concentration matter.
Designed for Nutrient Management
Red Sea recommends using Nitrate Pro alongside its Phosphate Pro Test Kit when accurately managing nitrate and phosphate, including when dosing Red Sea NO₃₄-X.
Monitoring both nutrients provides a much clearer picture of aquarium nutrient conditions than considering nitrate alone.
