Api Test Kit Ammonia 272075


If you have an aquarium, it’s important to keep the water clean and healthy for your fish. One of the most crucial components of a healthy aquarium is ammonia levels. Too much ammonia can be deadly for fish, so it’s important to regularly test the levels and take action if necessary. That’s where the API ammonia test chart comes in.

What is the API Ammonia Test Chart?

The API ammonia test chart is a tool that measures the ammonia levels in your aquarium water. It consists of a color chart that you compare to the color of your aquarium water after adding a few drops of the testing solution.

How to Use the API Ammonia Test Chart

Using the API ammonia test chart is simple. First, fill a test tube with water from your aquarium. Then, add a few drops of the testing solution and shake the tube. Finally, compare the color of the water to the colors on the chart to determine your ammonia levels.

Interpreting the Results

The color chart on the API ammonia test chart has four different colors that correspond to different levels of ammonia. The ideal level of ammonia in your aquarium is 0 ppm (parts per million). If your test shows a higher level than 0 ppm, you need to take action to lower the levels.

What to Do If Your Ammonia Levels Are Too High

If your API ammonia test chart shows that your ammonia levels are too high, there are a few things you can do. First, do a partial water change to dilute the ammonia levels. Second, make sure you’re not overfeeding your fish. Overfeeding can lead to excess waste, which can cause high ammonia levels. Finally, consider adding live plants or a biological filter to help break down the ammonia.

The Importance of Regular Testing

Regularly testing your aquarium water is crucial to keeping your fish healthy. Ammonia levels can fluctuate quickly, so it’s important to test often. Using the API ammonia test chart can help you catch any issues early and take action before it’s too late.


The API ammonia test chart is an essential tool for any aquarium owner. By regularly testing your ammonia levels and taking action if necessary, you can keep your fish healthy and happy. Remember to always follow the instructions on the chart and take any necessary steps to keep your water clean and healthy.
