Testing water parameters weekly helps prevent invisible water problems that can be harmful to fish. 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. Small amounts of ammonia stress fish; large amounts of ammonia kill fish. Ammonia is the #1 killer of freshwater fish. The API AMMONIA TEST KIT for freshwater and saltwater squariums contains two liquid dropper bottles, easy-to-read instructions with information on how to test and correct unsafe water conditions, two color charts and a test tube with snap-tight cap. This test kit reads ammonia levels from 0 to 8 ppm. Use the API API AMMONIA TEST KIT several times a week for 4-6 weeks when you start a new aquarium, and then use it weekly for monitoring or when problems occur. This aquarium test kit is for use in freshwater and saltwater aquariums.

Fill a clean test tube with 5 ml of water to be tested, or to the line on the tube. Add 8 drops from ammonia test solution bottle #1, holding the dropper bottle upside down in a completely vertical position to assure uniform drops. Next, add 8 drops from ammonia test solution bottle #2, holding the bottle the same way as bottle #1. Cap the test tube and shake vigorously for 5 seconds, then wait an additional 5 minutes for color to develop. Read the test results by comparing the color of the solution to the appropriate ammonia color card (either freshwater or saltwater). The tube should be viewed in a well-lit area against the white of the card. The closest match indicates the level of ammonia in the water sample. Rinse the test tube with clean water after use. Do not pour test tube contents back into aquarium or pond.

The dropper tips are all the same, but the viscosity of the liquids are different. Drops may appear to be larger coming out due to the thickness of the drop.
