Tetratest NH3 NH4 Total Ammonia Test Kit

Simple to use kit for determining ammonia levels.
Ammonia (NH3/NH4+) is excreted by fish directly into the water, and is also released from the breakdown of solid waste and uneaten food. Ammonia 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 ammonia level may become toxic. The only way to determine the ammonia level is by testing it with a TetraPond Ammonia kit. Regular testing, especially in new ponds, will prevent damage caused by ammonia poisoning.
