Fritz Nitrite Test Kit – 180 Tests (04002) is a water test kit designed to measure nitrite levels in an aquarium. Nitrite is produced during the ammonia cycle as nitrifying bacteria process ammonia. Although nitrite is not as immediately toxic as ammonia, buildup should be addressed promptly, since persistent nitrite exposure—even at low levels—can cause brown blood disease in fish. For most tanks that have an established biological filter and are progressing through the nitrogen cycle, nitrite is ideally zero, and regular testing helps you confirm that the cycle is working as intended.
Features:
- Measures nitrite so you can spot accumulation during the nitrogen cycle
- Helps you track the shift from ammonia-related waste processing toward completion of the cycle
- Supports timely action if nitrite rises, helping reduce risk to fish
- Useful for routine monitoring once your biological filter is established
- Based on the principle that nitrite will eventually be converted to non-toxic nitrate
