Nitrite test for marine and freshwater aquariums

The influence of nitrite on fish: Like ammonia (NH₃), nitrite (NO₂^-) is toxic to aquarium inhabitants. High levels of nitrite cause stress and affect the red blood cells of fish, reducing their ability to breathe, which can lead to death by suffocation.

What to do? When high levels of nitrites are detected, a partial change of water must be urgently carried out.
