About API Testing

Testing the Waters

For fish to thrive, their aquarium water must be similar to the water in their natural environment. Poor water quality can cause stress, illness and even the loss of your fish. Important water quality parameters include ammonia, nitrite, nitrate, and pH. These can vary over time, and they are invisible to the eye, which is why it is necessary to test weekly. Choose from a wide range of API testing options like the Freshwater Master Test Kit or 5-in-1 Test Strips to accurately evaluate your water.

Pressed for Time? Just Dip and Read

Simply dip an API test strip into your aquarium, swirl it twice, and then use the color-coded chart to determine if your water is within safe parameters or if adjustments are needed. That’s it! API test strips are available in a 5-in-1 version, which includes testing for pH, nitrite, nitrate, carbonate, and general hardness. Ammonia and pH test strips are also available so you can mix and match according to your needs.

The Scientific Approach

Get professional results from the comfort of your home with API test kits. Measure up to six parameters with API Master Test Kits, or pick and choose from a wide variety of individual test kits. Both types of kits come with test tubes and a laminated, calibrated color card. API test kits allow for numerous tests, making them an inexpensive way to help keep your aquarium water quality in check.

How to Correct Aquarium Water Parameters

Too Much Ammonia?

Ammonia is released into the water through gills, urine, uneaten food and more. API Ammo-Lock detoxifies it instantly.

Inappropriate pH Levels?

Fish require a specific pH level to thrive. Use API pH Down to lower freshwater aquarium water pH to the right level.

Too Much Nitrite?

Use API Quick Start to quickly consume nitrite and help maintain an active biological filter.

Nitrates Too High?

API Nitra-Zorb helps remove nitrate and other toxins that can be harmful to fish and lead to algae growth.

Perfect to test cat urine

I'm using this product off-label. Its broad range of pH is helping us follow our cats' urine pH which has been too often just over 7.0 (neutral). If a product

I'm using this product off-label. Its broad range of pH is helping us follow our cats' urine pH which has been too often just over 7.0 (neutral). If a product is helpful for an unintended use, why not use it?

Discus Tanks

This test kit is accurate for the ph in my discus tanks. i needed this test kit because i keep my ph at 6.2 and this test kit goes down to 5.0. I also checked it

This test kit is accurate for the ph in my discus tanks. i needed this test kit because i keep my ph at 6.2 and this test kit goes down to 5.0. I also checked it with a scientific ph test kit to make sure the API Test kit was accurate. It was right on spot. I only use the Liquid test kits the dip strips are not that accurate. Thank You Joe H Navy Seabee

Not accurate

I’m not sure if the chemicals got wrecked because of the insanely hot weather or what happened but this is not accurate at all. It says my ph is 8.9 but I know that

I’m not sure if the chemicals got wrecked because of the insanely hot weather or what happened but this is not accurate at all. It says my ph is 8.9 but I know that my ph is always between 7.0 and 7.4
