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.


Find Your Ideal Testing Style!

Your API Test Options

Choose the test method that works best for you. Whether you’re a bit pressed for time, or you prefer to measure your parameters on a more in-depth scale, or you only need to test one or two specific parameters, API has what you need!

Dip and Read

Just dip a 5-in-1 TEST STRIP in your aquarium, swirl twice, and compare to our color chart for fast and accurate results.

The Scientific Approach

For more detailed analysis, use the FRESHWATER MASTER TEST KIT, POND MASTER TEST KIT, SALTWATER MASTER TEST KIT, or REEF MASTER TEST KIT for precise readings of parameters.

Pick One (or Two)

Need to check your phosphate levels? What about ammonia? API offers specific test kits to test many different parameters, from general hardness and copper to pH and nitrate. Grab the one you need for a streamlined approach to testing.

What comics have been missing for years that has made collecting them a drag has been the loss of single issue tales that connect to a larger story. This has it as well as some great art and bat electric gauntlets. I love it. Can’t wait to read more.

Amazing

What can I say about this Absolute series other than it being absolutely perfect! All of them in the whole series are a very good read. They are colorful and artistic, and the stories are great! I was starting to get worried about comics before these came out because they were starting to get boring but wow, these are amazing.
