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.

Questions & Answers

3 Customer Questions


What’s the difference between freshwater testing strips and pond test strips? I have multiple tanks including freshwater, saltwater, and a pond so I’d rather get the freshwater and saltwater strips to measure them all unless freshwater strips don’t measure ponds?

Answer by ChewyJul 19, 2021
All testing strips can be used interchangably as long as you follow the correct color chart if it is freshwater or saltwater.

Looking at API 5 in 1 test strips. Seems like I still need to buy something to test for Ammonia too?

Answer by ChewyApr 23, 2020
These test strips do not measure Ammonia levels.

Does this kit also work for testing oxygen levels?

Answer by ChewyJan 18, 2018
The 5 in 1 Test Strips only measures PH, Nitrite, Nitrate, Carbonate Hardness and General Hardness.

Not easy to understand

This product is good but not easy to understand the scale and what you need to correct the water problem. The instructions are vague and not very helpful.
