Salifert Nitrite Test Kit for Marine Aquariums
The Salifert Nitrite Profi Test Kit is designed for accurate detection of nitrite levels in marine aquariums. In a properly cycled aquarium, nitrite is converted to nitrate and then, in oxygen-deprived areas such as live rock and filter media, it may be reconverted to nitrite before being transformed into harmless nitrogen gas.
- Many nitrite test kits experience interference from amines, such as naturally occurring and essential amino acids, which can lead to falsely low readings—especially at low nitrite concentrations.
- The Salifert Test Kit features a unique formulation that avoids amine interference, providing reliable and consistent results.
- Color development occurs fully within one minute, and the resulting color is intense, enabling precise detection of even trace nitrite levels.

I’ve used this test kit for several months now and it’s been very reliable. The color change is clear and easy to read, even at low nitrite levels. No false negatives like I’ve had with other kits. Great for monitoring my reef tank.

The instructions are simple and the test strips work consistently. I appreciate that it doesn’t react to amino acids, which has been a problem with other brands. My nitrite levels are now under control.
Trevor Fraser –
It’s accurate and fast. I only wish the package included more test strips. Otherwise, it’s a solid choice for marine aquarium maintenance.
