Elos Aqua Test Ammonia

Elos Aqua Test Ammonia
Elos Aqua Test Ammonia

Ammonia is the most lethal form of inorganic nitrogen produced in aquarium water.
The major source of ammonia in a well run aquarium is from solid waste from fish and invertebrates, uneaten food and decaying leaves of plants.
Nature comes to our rescue as there are specialized bacteria (Nitrosomonas species) that “eat” ammonia , and strip away the hydrogen atoms.This bacterial population may be affected by many negative biochemical events.
In an established aquarium Ammonia should be zero, for these reasons, the periodical analytical valuation of ammonia in the aquarium water should be considered by the serious aquarium enthusiast.

ELOS AquaTest NH4, as well as all the other colorimetric test kits of this line, grants high accuracy thanks to several procedures. The precision of a colorimetric test kit is, in fact, strictly related to the precision of the color chart. In these tests we use “RealColor” technology. An accurate system to calibrate the colors chart compared to the reagents, on each production batch. In combination with the use of NIST (National Institute of Standard and Technology) certified samples, this grants high accuracy and constant test results.

Thanks to the use of Lab Quality reagents, our NH4 test, allows the determination of the Ammonia down to a level of only 0.05 mg/lt, really alerting to an Ammonia presence, thus preventing delicate situations that may occur especially in reef aquarium.

Test kit reagents are very delicate, their accuracy is significantly influenced by storage. Ammonia reagents are, together with Nitrite and Nitrate reagents, the most delicate ones and can be strongly influenced by stocking procedures/time. For this reason we keep our stock strictly under control and we suggest, to all our retailers, to do the same in order that on the shelves ONLY the most actual and fresh production batch is available. When you purchase a test kit be sure to check the Best Before Date.


  • Easy reading:RealColor” technology.
  • High precision: thanks to the use of a 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.
