Tetra Test Nitrate Test Kit

Tetra Test Nitrate (NO3) is a simple to use kit for determining nitrate levels. It is a liquid kit which works by changing the colour of a water sample in relation to the nitrate concentration. You simply need to compare the colour of the sample to the easy-to-read colour chart in order to determine the nitrate level. Tetra recommend testing the nitrate level every 1-2 weeks.
