LaMotte® Test Kits: Ammonia Nitrogen, The test kits measure total ammonia. Total ammonia consists of both nontoxic NH4+ (ionized) and toxic NH3 (un-ionized) forms. The proportion of one to the other is variable. The toxic form increases in proportion as the pH and/or temperature increases.
Ammonia builds up in the water primarily by the metabolism of protein (nitrogen). About 10% of the protein fed to fish will show up as ammonia in the water. LM3304 is saltwater only ( Note: Water containing Ammo-Lock® and other ammonia-removing chemicals should be tested using an ammonia kit (LM3304) that uses the salicylate method (0 to 2.0 ppm).
