Zoolek Aquatest NO2

The test allows you to measure the content of nitrites (NO2) in fresh and saltwater aquariums in the range of 0-10 mg / l. The content is enough to run 50 tests.

The nitrite test is especially recommended in cases where there are problems with the so-called closing the nitrogen cycle. High levels of nitrite are harmful, so it is important to keep them under control.
