Simple to use kit for determining nitrite levels.
Nitrite (NO2-) 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 ponds, or if the filter bacteria are damaged, the nitrite level may become toxic. The only way to determine the nitrite level is by testing it with a TetraPond Nitrite kit. Regular testing, especially in new ponds, will prevent damage caused by nitrite poisoning.
Application
The TetraPond Nitrite kit is a liquid kit, which works by changing the colour of a water sample in relation to the nitrite concentration. You simply need to compare the colour of the sample to the easy-to-read colour chart in order to determine the nitrite level.
If nitrite levels are high then you should seek advice as to the underlying cause.
