API Freshwater Master Test Kit - API

Test your aquarium water at least once a week, or more frequently if you are setting up a new tank, adding new fish, or suspecting a problem.

The kit measures pH (acidity/alkalinity), High Range pH, Ammonia (toxic waste), Nitrite (toxic waste), and Nitrate (less toxic waste).

Perform a partial water change immediately (25-50%), and monitor the levels closely. Consider using a water conditioner to detoxify the ammonia/nitrite.

The ideal pH range typically falls between 6.5 and 7.5 for most freshwater aquariums. Regular water changes and the addition of buffering agents can help stabilize pH.

The test solutions have an expiration date printed on the bottles. Always replace expired solutions to ensure accurate results.

No, this kit is specifically designed for freshwater aquariums. Use a saltwater test kit for saltwater environments.

Nitrates are the end product of the nitrogen cycle and, in high concentrations, can be harmful to fish. Regular testing and partial water changes help keep nitrate levels manageable.

Ensure you are using the correct lighting and viewing the test tube from the top. Compare the colors in a well-lit area, preferably with natural light.

Double-check the expiration dates of the test solutions and make sure the testing procedure is being followed exactly. Ensure you have the correct sample size for accurate results.

Check for any recent changes in the aquarium, such as new additions, changes in feeding habits, or medication. Perform a partial water change and retest.
