Elos Aqua Test Kit - Nitrite Information

Product Manuals & Documentation

The Elos Aqua Test Kit (Nitrite) from Pet Store allows you to know the concentration of nitrite presence in your aquaria, fish ponds and other artificial water systems. As you know, nitrite decomposes the hemoglobin in your fish tanks, reducing its oxygen and endangering your marine life. Even without this function nitrite is still harmful to your pets, and a single particle of it can poison your fish. With the nitrite test kit, you will alleviate these risks, giving your pets a safer home.

Created with extreme precision and tried and tested in labs and water systems, this product has everything you need to know nitrification activities in your aquarium. The kit features a RealColor technology that makes it extremely easy to use and the results not difficult to read. It is a high-precision instrument, thanks largely to its calibrated droppers. Moreover, each reagent in this product is non-toxic and harmless to your aquatic pet's home and is NIST approved and recommended.

Stop the growing presence of nitrite particles now! With the Elos Aqua Test Kit (Nitrite), you are ensured that your aquarium and your pets are free from excessive nitrification and safe from its harmful elements. This product is available in online and local pet stores. It is highly esteemed and recommended by aquatic lovers.


The activity of the bio-filter in the aquarium system can be divided by mineralization and nitrification. The product of the mineralization process is ammonia and organic acids. The next step of decomposition is the oxidation (nitrification) of ammonia and ammonium to Nitrite (NO2). Nitrite has a toxic effect on fish because it oxidizes hemoglobin to methemoglobin. While hemoglobin is responsible for the transport of oxygen, methemoglobin lacks this ability! Nitrite concentrations higher than 0.05mg/L (ppm) of NO2 are not acceptable keeping aquarium fishes. For these reasons, the periodical analytical evaluation of nitrite in the aquarium water should be considered, especially during the aquarium set-up and periodically to avoid the activity loss of the bio-filter system.

ELOS AquaTest NO2, as well as all the other colorimetric test kit of this line, grant very high precision thanks to several procedures like the use of “RealColor” technology, an accurate system to calibrate the color chart compared to the reagents; the validation of each reagent with NIST (National Institute of Standard and Technology) certified samples and the careful stock management to supply to our customers ONLY the freshest production batch.

    Experience Level: Intermediate

    Comments: Very simple to use. Colors are easy to distinguish and the range of values goes from low to high with plenty of intermediate values: 0, 0.02, 0.05, 0.1, 0.2, 0.5, 1, and 2. Just make sure to read the color looking straight down into the test tube and hold the tube about 1/2 inch above the card.
