The Biological filtration is a method that uses naturally occurring nitrifying bacteria to detoxify nitrogenous wastes. One type of bacteria (Nitrosomonas spp.) converts ammonia to nitrite while another naturally occurring bacteria (Nitrobacter spp.) converts the nitrite into a far less harmful form of nitrogen waste: nitrate. Nitrate is the final stage of the nitrification process. Many invertebrates, unlike fish, are not tolerable to high nitrate concentrations. As a result, it is extremely important to make sure that nitrate levels do not reach high levels. In freshwater aquaria the optimal level of Nitrate should be below 20 mg/lt. Values of over 75 mg/lt should be avoided at all costs. In reef marine aquarium their level should not exceed 20 mg/l. A level of 10 mg/lt is the maximum for reef aquariums. For these reasons, the periodical analytical valuation of nitrate in the aquarium water should be considered, specially during the aquarium set-up and, periodically, to avoid a too high level inside the water of our aquaria. Our kit allows the determination of the Nitrate level within a range of 5 – 75 mg/Lt ELOS AquaTest NO3, as well as all the other colorimetric test kit of this line, grants an high precision thanks to several procedures like the use of “RealColor” technology, an accurate system to calibrate the colours chart compared to the reagents; the validation of its quality, thrugh NIST (National Institute of Standard and Technology) certified samples, in order to grant accuracy and constant results; the carefull stock management to supply to our customers ONLY the most actual and fresh production batch.
HIGHLIGHTS: Easy reading: “RealColor” technology. High precision: thanks to the use of calibrated dropper NIST validation: each batch is validated using NIST (National Institute of Standard and Technology) samples "Safe reagents": reagents and testing procedures are based on Low Risk Reagents. None of our test kit are based on Toxic Reagents.
Note: if the NO3 value is too high, we recommend a partial water change. Periodical check on water quality can help to pinpoint causes of deviations in NO3 value and can prevent fish and invertebrates being harmed.
