Seachem Ammonia Alert

Seachem Ammonia AlertAmmonia Alert™ is an innovative color device for continuously detecting and monitoring toxic free ammonia. A sensor changes reversibly from yellow to green to blue, relative to the ammonia concentration. No test kits, chemicals, or procedures are needed. The device detects less than 0.05 mg/L (ppm) free ammonia and alerts you to the #1 killer before any sign of stress. It lasts over a year. Marine or freshwater use.

In the absence of free ammonia the unit will assume a yellow or faint yellow-green color. It is normal for the dry sensor to have a greenish hue. It may take up to a few days for a dry sensor to equilibrate with the water. No sampling of water, chemicals, or test procedures are required. The presence of the free ammonia is detectable continuously with a response time of about 15 minutes. Response to decreasing ammonia is slower, requiring about 4 hours to go from TOXIC to SAFE on removal of ammonia.

Seachem MultiTest Ammonia

Seachem MultiTest Ammonia 75 TESTS

This kit measures total (NH3 and NH4+) and free ammonia (NH3 only) down to less than 0.05 mg/L and is virtually interference free in marine and fresh water. Free ammonia is the toxic form of ammonia (vs. ionized Ammonia NH4+ which is non-toxic) and thus it is much more important to keep an eye on the level of free ammonia in your system. This kit is based on the same gas exchange technology that is used in the Ammonia Alert™ and thus is the only kit on the market that can read levels of free ammonia while using ammonia removal products such as Prime®, Safe™, AmGuard™ and any similar competing products. The other kits (salicylate or Nessler based) determine the total ammonia by raising the pH of the test solution to 12 or greater. At this high pH all ammonia removal products will breakdown and rerelease the ammonia, thus giving you a false ammonia reading.

Elos AquaTest NH4 - Ammonia/Ammonium Test Kit

Elos AquaTest NH4 - Ammonia/Ammonium Test Kit

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 of fish and invertebrates, uneaten food, decaiyng leaves of plants.

Nature comes to our rescue as there are specialized bacteria (Nitrosomonas species) that “eat” ammonia , and strip away the hydrogen atoms. By the way, this bacterial population may be affected by many negative biochemical events.

In an established aquarium Ammonia should be zero, for these reason, the periodical analytical valuation of ammonia in the aquarium water should be considered by the serious aquarium enthusiast.
