sera nitrite-Test (NO2)

The sera NO2 test is a water test for checking the nitrite content in fresh and saltwater aquarium, as well as in garden ponds.

Nitrite is produced in the aquarium and garden pond as an intermediate degradation product of the fish excrement. Too much nitrite is dangerous. Nitrite is produced from ammonium and is broken down by the filter bacteria to nitrate. Therefore, in addition to the nitrite content, ammonium and nitrate levels should also be checked regularly.
