Nitrite is one of the most toxic nitrogen forms and it can cause severe mortality of fish in the aquariums as well as in the fish ponds/tanks.

Nitrite is an intermediate in the oxidation of ammonium to nitrate, a process which is carried out naturally and by the bacteria in biological filters Nitrosomonas spp. converts ammonium to nitrite. Nitrobacter spp. converts nitrite to nitrate.

Alkaline conditions lead to a higher amount of un-ionized ammonia, and this, in turn, has a greater inhibiting action on Nitrobacter than on Nitrosomonas spp. Thus alkaline water see an increase in nitrite levels. Other parameters which affect the bacteria differently also have an impact. Nitrite is actively taken up by the gills (chloride cells probably) and blood levels maybe 10 times those of the surrounding water. Nitrite oxidizes the iron in haemoglobin to form methemoglobin and this pigment lacks the ability to bind reversibly to oxygen. Grossly, high levels of methemoglobin result in a brown colour to the blood and results in so-called “brown blood disease”. Erythrocytes of fish have a reductase which reconverts methemoglobin to haemoglobin but this takes 24–48 hours if fish moved to normal water. Nitrite also causes a leukopenia, and although in the short term this is probably inconsequential, in the long term with chronic low-level exposure, it may increase susceptibility to disease.

Tolerance to nitrites increased when the concentration of ascorbic acid was high in the diet (Blanco & Meade, 1980)

Lifesonic Nitrite Kit is a color chart comparison water testing kit that provides the value of nitrite in your Aquaculture Pond/ Aquariums/ Tanks. The approximate number of tests per package is 150.


Lifesonic Nitrite Test Kit employs a calibrated colorimetric method of testing the actual content o oxygen in the water. Unlike other test kits, this kit is optimized to give readings in 5 minutes. The kit is claimed to give nearly 150 test results.
