Tetra Test NO2 Water Treatment (2x10ml)

The Tetra Test Nitrite Water Test Kit is a simple to use kit for measuring the Nitrite value (N02) reliably and precisely in freshwater aquariums, marine aquariums and ponds. The Tetra Nitrite Test Kit provides readings between 0.3 mg/l and 33.0 mg/l. Organic, nitrogen containing substances in ponds and aquariums, such as fish waste and uneaten food, are decomposed in stages via the Nitrogen Cycle: first into toxic Ammonia, then into Nitrite and finally into Nitrate. A Nitrite concentration of over 0.3 mg/l will cause your fish long term harm, with higher concentrations leading to stress and possible fatal consequences. Testing for Nitrite especially in new set ups is important so you can take appropriate action if required.
