Nitrite Checker For Koi Ponds Nisai & Older 5mmWeight 64gIt's essential to monitor the most common toxic pollutants in your pond regularly, and to monitor more frequently when your pond is going through a big change such as a change of seasons, introducing new fish, initially starting a pond, or after extreme weather conditions. The two most common toxic pollutants that can damage your koi, or even kill your koi, are ammonia and nitrite. Losses due to high ammonia or nitrite are unfortunately too common.
