Nitrite Checker For Koi Ponds

It'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.  High ammonia and nitrite levels can be easily dealt with by a properly sized and maintained filter, and water changes.  So knowing the level of ammonia and nitrite is important for understanding the immediate danger to your koi, and also to understand how well your filters are performing.

The Ammonia Checker and Nitrite Checker we supply are a simple, accurate and cost effective way to measure and monitor the levels of these toxic pollutants.  This will help you keep healthy koi and maximise enjoyment from your pond.
