Seachem MultiTest Ammonia

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 may be used with freshwater or marine water. Unlike other kits on the market, the chemical basis for this test assures that interference from other substances is highly unlikely. MultiTest™ Ammonia performs over 75 tests and contains a reference sample for validation.

• Measures total and free ammonia down to less than 0.05 mg/L
• Multi-cavity plate for simultaneous testing of up to 6 tests at the same time
• Includes reference for test validation
• Marine or Freshwater

Seachem Sensor Technology

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. 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.
