Nitrites (NO 2 ) are among the most toxic substances for fish in the aquarium. They can accumulate in water when biological filtration is deficient.
The sera Test NO 2 can be used to easily and reliably determine the nitrite content in fresh and salt water.
For slightly higher nitrite levels, we recommend using sera bio nitrivec (freshwater), sera marin bio reefclear (seawater) or sera pond bio nitrivec (pond).
In the event of heavy nitrite pollution, sera toxivec (fresh water) or sera pond toxivec (pond) act quickly.
Sufficient for approximately 75 measurements.
