Nitrite is produced from the breakdown of ammonia in the filter. Nitrite is highly toxic to fish, but is usually removed from the water by the bacteria which live inside the filter. However, in new aquariums, or if the filter bacteria are damaged, the nitrite level may become toxic. The only way to know what the nitrite level is, is by testing the water.
Regular testing, especially in new aquariums or ponds, will prevent damage caused by nitrite poisoning.
An optimal level of nitrite in any tank is simply 0mg/L, when the nitrite level is 0.5mg/L or higher it means there are not enough bacteria present.
