Nitrite is a product of ammonia and nitrogen that is not completely oxidized. Its toxicity is very strong, especially with the decrease of pH value. The reason why nitrite is generated is mainly due to the lack of oxygen and ammonia nitrogen-converting microorganisms in the presence of ammonia nitrogen. So that the ammonia nitrogen is not converted into nitrate which the plant can absorb and is converted into nitrite state.
The content of nitrite in the water of cultured ornamental fish should be controlled below 0.05 mg/L.
With help of Aquarium Pure, the nitrite will be removed to a very low level soon and fishes will be vigorous again.
