API NITRITE TEST KIT
Nitrite is produced in the aquarium in the forms of fish waste, uneaten food, and by nitrifying bacteria in your aquarium’s natural cycle as it breaks down ammonia. Low levels of nitrite inhibit respiration and suppress the immune system, while high levels cause suffocation in fish. The API® NITRITE TEST KIT reads nitrite levels quickly and accurately in your tank, and tests parameters from 0 to 5 ppm.

I’ve used this kit for three months now and it’s very reliable. The color chart is easy to read and I can spot nitrite levels quickly. It helps me maintain a healthy environment for my fish.

The test results match what my aquarium monitor shows. I appreciate the included instructions and the durability of the glass test tube. Only minor improvement would be a more compact design.

Great value for the number of tests. I test my tank weekly and it’s easy to use. No issues with accuracy or clarity of the color chart.
