Ammonia test kit. Measures ammonia to prevent fish loss.

Spending a few minutes each week maintaining and monitoring aquarium conditions is key to a healthy aquarium. Tropical fish constantly release ammonia into the aquarium through their gills, urine, and solid waste. Decayed food and decomposing organic matter also add ammonia to the water. Large amounts of ammonia will kill fish. Ammonia is the number one killer of tropical fish.

The API® AMMONIA TEST KIT is a mercury-free salicylate test for freshwater and saltwater fish. The AMMONIA test checks ammonia levels from 0 to 8 ppm.
