API Ammonia Test Kit
API Ammonia Test Kit measures ammonia to help prevent fish loss. It is mercury-free, salicylate test for fresh and saltwater fish. It tests ammonia levels from 0 to 8 ppm.
Tropical fish continually release ammonia into the aquarium through their gills, urine and solid waste. Uneaten food and decaying organic matter also add ammonia to the water. Even small amounts of ammonia stress fish; large amounts of ammonia will kill fish. Ammonia is the number one killer of tropical fish.
