Why Test for Nitrite?
Fish, frogs, birds, and other pond animals release solid waste into the pond water. This waste is turned into toxic ammonia. Nitrifying bacteria in the pond convert toxic ammonia to nitrite (also toxic). Nitrite is then converted to nitrate.
Newly set up ponds have not developed sufficient nitrifying bacteria to detoxify ammonia and nitrite. Ammonia and nitrite will accumulate when the pond is initially set up, especially if fish are added. Overstocking with pond fish, as well as excessive uneaten food and decomposing vegetation can cause excessive nitrite levels. Some pond plant fertilizers contain nitrite or ammonia. Nitrite is highly toxic to pond fish.
