Testing the Waters

In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even loss. Most common water quality parameters are Ammonia, Nitrite, Nitrate, and pH. All may vary over time and all are invisible to the eye which is why it is important to test weekly. Testing aquarium water weekly will aid in keeping your most important water parameters within the proper range for your aquarium. Choose from a wide range of API testing options, such as our popular FRESHWATER MASTER TEST KIT or 5-IN-1 TEST STRIPS, for accurate water evaluation. Regular testing will help you easily determine your aquarium conditions.

Product Description

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.

With API aquarium products, it’s easy to keep a beautiful saltwater, freshwater or reef aquarium. For almost 60 years API has developed premium solutions with proven and effective results for your family and ours. API offers a range of testing kits, water conditioners, and nutritionally superior food, because we’re dedicated to making a better underwater world. They work to provide a safe, hospitable environment for fish such as tropical community fish, cichlids, goldfish and more. At API, we understand the rewards and relaxation of fishkeeping because we have a passion for fish too.

Please Read Instructions Before Use

Ingredients

polyethylene glycol

Directions

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.

5 Stars
Great, affordable product!
I bought this kit because I had a Betta with what appeared to be fin rot. I suspected it was actually fin biting, but decided to monitor the tank's ammonia levels anyway. This kit is by far the most economical - for the amount of tests included for the price.After 2 weeks of 0-.25 readings without fluctuation, I wondered if the tests were even accurate. I decided to test 5ml of pure ammonia instead. Imagine my disappointment when the pure ammonia sample turned the same yellow (0%). Before you go sending hate mail to API, there's a good reason for this. It turns out, the ammonia level was too high and essentially "blew out" the testing liquid. API is assuming your fish isn't living in pure ammonia and, therefore, didn't make this kit to test levels that high.Next, I tested 5ml of water from a 1 gallon jug filled with tap water and 1 drop of pure ammonia. Yes, I apparently have too much time on my hands and a latent mad scientist gene. This test proved accurate. The tube turned dark green almost instantly (picture attached). I feel much more secure using and believing this test now.
