SERA Nitrite Test
The SERA Nitrite Test allows you to accurately measure the concentration of nitrite (NO2) in both freshwater and saltwater, one of the most toxic substances for fish. When biological filtration is insufficient, nitrites can accumulate in the water and harm fish health.
With this test, you can easily monitor nitrite levels and ensure that the aquarium environment is safe. If nitrite levels are slightly elevated, it is recommended to use Sera Bio Nitrivec (freshwater), Sera Marin Bio Reefclear (saltwater), or Sera Pond Bio Nitrivec (pond). For high nitrite concentrations, Sera Nitrit-minus provides a quick and effective solution.
This test is sufficient for approximately 75 readings.
