Test for Nitrite (NO2)
Nitrite (NO2) is among the most toxic substances for fish in aquariums. It can enrich in the water in case of insufficient biological filtration.
The sera NO2-Test allows monitoring the nitrite level in fresh and marine water easily and reliably.
Sufficient for approx. 75 measurements.
Nitrite is formed as an intermediate product during the breakdown of fish waste.
Too high nitrite levels endanger the fish.
Nitrite is formed from am-monium and is converted into nitrate by bacteria in a functioning filter.
Therefore also ammo-nium and nitrate should be checked regularly.
