Multitest Nitrite & Nitrate

The set is designed to measure the level of nitrites and nitrates in freshwater and sea aquariums. It allows you to evaluate the amount of nitrites (NO2 -) and nitrates (NO3 -), no nitrogen. Nitrites are toxic compounds for living organisms and should not occur in a mature tank. Nitrates are less harmful, but their level should remain below 20mg / l.
The test is enough for over 75 measurements.
