Sera Testing Nitrile Content in Water NO2

For easy determination of nitrite content in freshwater and seawater
Nitrite (NO2) is one of the most toxic substances for fish in the aquarium. It can accumulate in the water when biological filtration is deficient.
The sera Test NO2 allows easy and reliable determination of nitrite content in freshwater and seawater.
For slightly elevated nitrite levels, we recommend sera bio nitrivec (freshwater), sera marin bio reefclear (seawater) or sera pond bio nitrivec (pond). For heavy nitrite pollution, sera Nitrite-minus acts quickly.
Sufficient for approximately 75 measurements.
