ELOS AQUA TEST KIT- NITRITE
Naturally occurring nitrifying bacteria detoxify nitrogenous wastes using biological filtration. 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.
Nitrite is the extremely toxic intermediate stage for fish and invertebrates. As the level of nitrite increases, the function of hemoglobin necessary for the transport of oxygen in fishes` blood gets blocked. Lethal concentrations cause chronic stress which lowers the fish`s resistance to parasite and bacterial attacks, reducing food intake and growth, and can result in death. It also causes damage to fishes` natural barriers and can stimulate cancer in the digestive system.
Nitrite levels in excess of 0.1 mg/L are considered dangerous to many ornamental fish. For invertebrates, levels higher than 0.05 mg/lt are toxic. If the biological filtration process is impeded, for example by new filter material, this can lead to harmful rise in the nitrite ion concentration. For this reason, regular use of a nitrite test kit is an absolute requirement.
ELOS America is the USA branch of a time-honored tradition. ELOS has been in business in Europe for over 25 years, and is recognized as one of the most innovative leaders in the aquarium industry. In 1997, ELOS was the first to discover that in closed systems, some species of corals (mainly SPS) significantly benefit (better colors and more rapid growth) from a reduced addition of organic additives (dissolved organic material), but only when compensated by a selective addition of high quality nourishment. Based on our groundbreaking and innovative research, ELOS introduced to the market a "Trio" of products to feed our corals – Omega (Amino Acids), SvC (planktonic Coral Food) and Pro-Skimmer (Carbonate Source).
ELOS was also the very first company to produce LED lights for the aquarium, the first to produce a rimless tank, the first to use probiotics in our foods, and numerous other firsts. ELOS is committed to providing high quality products to the aquarium industry and customers quickly recognize our dedication to not only advancing the hobby through research and innovation, but also our dedication to elegant simplicity in design and use. With the addition of a dedicated staff and warehouse in the USA, we are renewing our commitment to provide our customers with the best possible solutions and products available.
