Seachem MultiTest™ Nitrite & Nitrate Test Kit
Measures nitrite to less than 0.1 mg/L and nitrate to less than 0.2 mg/L.
- Multi-cavity plate allows simultaneous testing of up to 6 samples
- Includes reference solution for test validation
- Compatible with both marine and freshwater aquariums
Nitrite is toxic and should be undetectable in a well-established aquarium. During the cycling phase, nitrite levels may exceed 20 mg/L. Nitrate is less toxic but it is recommended to keep levels below 20 mg/L for optimal water quality.
| Parameter | Measurement Range |
|---|---|
| Nitrite | Less than 0.1 mg/L |
| Nitrate | Less than 0.2 mg/L |
