  • Reads Nitrite levels fast and accurate

Follow API Easy Care Guide and use the NITRITE TEST KIT:

  • During Regular Care
  • When addressing Water Problem Solving issues

Taking a few minutes each week to maintain and monitor aquarium conditions is the key to a healthy aquarium.   Nitrite is produced in the aquarium by fish waste and uneaten fish food.  Toxic nitrite is produced by nitrifying bacteria in the biological filter as it breaks down ammonia. Low levels of nitrite inhibit respiration and suppress the immune system; high levels cause suffocation.  The NITRITE TEST KIT tests for harmful nitrite levels from 0 to 5 ppm.  For use in freshwater and saltwater aquariums.
