Product description

Most water problems are invisible to the eye. Quickly measure and modify the six aquarium levels that are most important to the health of your freshwater fish with the API FRESHWATER MASTER TEST KIT. To stay healthy and thrive, fish need properly balanced levels of ammonia, pH, high range pH, nitrite and nitrate. These levels can change rapidly and create harmful conditions when fish waste, uneaten food or other organic matter accumulate, or when untreated water is added. If left uncorrected, all of these can be harmful or even fatal to fish, with consequences such as reduction of oxygen, increase in stress and higher risk of disease. The API FRESHWATER MASTER TEST KIT measures these six parameters with scientific accuracy and provides professional results. It comes with four test tubes, a holding tray and computer calibrated, laminated color card. Just fill the test tubes, add the test drops and compare results to the color card. Then follow the recommendations on the card if action is required.

Frequently Asked Questions (FAQs)

Why test pH?

pH is the measure of acidity in your water. A pH reading of 7.0 is neutral, a pH higher than 7.0 is alkaline, and a pH lower than this level is acidic. It is important to keep your aquarium at the appropriate pH level to ensure optimal water quality for your specific fish species, as different types of fish require different pH levels for their habitats. API® FRESHWATER MASTER TEST KIT will enable you to test the pH levels in your water as often as needed!

Why test for Ammonia?

Fish continually release ammonia directly into the water through their gills, urine, and solid waste. Uneaten food and other waste also add ammonia to the water. A natural way that your aquarium handles this ammonia is through the biological filter, or natural aquarium cycle. However, as with any natural processes, imbalances can occur. This is why it’s important to regularly test for the presence of ammonia, which can spike unexpectedly in your aquarium. As soon as it is detected, ammonia should be removed, otherwise it will damage your fish’s gill membranes and harm their respiration, which can eventually result in fish death. Even small amounts of ammonia stress fish, suppressing their immune systems and increasing the likelihood of disease outbreaks. You can remove ammonia from your tank by performing a partial water change, and by dosing with a solution specifically designed to treat ammonia. Test frequently for high ammonia using API FRESHWATER MASTER TEST KIT.

Why test for Nitrite?

Testing for the presence of toxic nitrite is essential, so that if it is detected, steps can be taken to remove it. If left untreated, nitrite in the water will hinder normal fish respiration, eventually leading to fish death. Even small amounts or low levels of nitrite stress fish, suppressing their immune systems and increasing the likelihood of disease, which is why it’s important to test for nitrite using API FRESHWATER MASTER TEST KIT. You can remove nitrite from your tank by performing a partial water change.

How do I care for and clean my test tubes?

How hard do I shake the test tube when performing the tests?

While it is important to shake the indicated reagent bottles very vigorously, you should be gentler when shaking the test tubes during testing. Before shaking, make sure that the cap is closed tight. Place a finger or thumb on top of the cap, to make sure it cannot come undone during use. The goal of this shaking step is to mix the contents of the tube together and this can be accomplished by simply inverting the test tube, back and forth every 1-2 seconds, for the indicated amount of time.
