Elos Expert Line High-Resolution Aqua Test Kit – Nitrate HR

Item #: 0715


In nature the population of zooxanthellae is controlled by the level of nutrients (nitrates and phosphates) present in the water.  However, in a modern reef aquarium environment the control of zooxanthellae, through the reduction of nutrients (nitrates and phosphates), is the best way to get natural coloring of the corals. This has led to the creation of a multitude of “Management Methods” (Low Nutrients / Ultra Low nutrients).

Whether you are using microbiological methods or more traditional methodologies, it is necessary to keep consistent levels of nitrates and phosphates. ELOS AquaTest NO3-HR is specifically designed to assist you in tracking those levels.

The precise colorimetric scale with DUAL RANGE, allows you to read nitrate levels in a range between 0 and 4ppm with a minimum reading of only 0.15 ppm of nitrate. Used in conjunctions with the ELOS AquaTest Phosphate HR, assures you have the best system for full control of the level of nutrients.

Manufacturer Info

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.
