Nitrite is highly toxic to fish, but is usually removed from the water by the bacteria which live inside the filter. However, in new tanks, or if the filter bacteria are damaged, the nitrite level may become toxic. Regular testing, especially in new aquariums, will prevent damage caused by nitrite poisoning.
