API Freshwater Master Test Kit, Kit includes laminated color card, 4 test tubes & holding tray

Product Information

You need to keep an eye on the water quality and monitor all the visible and invisible changes that directly impact the inhabitants of your aquarium. This is a 5-in- 1 testing kit that allows you to do that. Cap the test tube and shake vigorously for 1 minute. This step is extremely important to ensure the accuracy of test results.

Note that when they say to wait for 5 minutes, this is the minimum time you need to allow for the color to change in the solution. In my observation, you can read the results any time after this; even up to hours later, the color holds the same. By the time I finish the last test, it has often been almost 5 minutes of wait time for the first test (Nitrate).Taking a few minutes each week to maintain and monitor aquarium conditions is the key to a healthy aquarium. The FRESHWATER MASTER TEST KIT tests the parameters that affect the health of freshwater fish: pH, High Range pH, Ammonia, Nitrite and Nitrate. The FRESHWATER MASTER TEST KIT is highly accurate and economical, and includes a computer calibrated, laminated color card, 4 test tubes and holding tray. The FRESHWATER MASTER TEST KIT comes with a complete, step-by-step instruction booklet, including information on how to correct unsafe water conditions. I am very happy with the accuracy observed. I get consistent results that I can trust. As long as you follow instructions, you will be rewarded with accurate results. The real positive of the liquid master test kit is the pricing. It is a bit tough to breakdown the number of available tests in the bottles. API advertises ‘over 800 tests’ but this is for all the separate tests combined. Each bottle has 37ml of fluid, but they each utilize different numbers of drops per test. I think the Nitrate test would run out first and I estimate that it would be good for around 80 tests. Other tests would last much longer. The FRESHWATER MASTER TEST KIT measures pH, high range pH, ammonia, nitrite, and nitrate in your freshwater aquarium.

I’m very happy with how API’s test kit works. It is cumbersome the first few times you perform all the test, but again, it gets faster and easier with practice.

Every parameter has different instructions, so you need to be accurate while following the steps. However, all the bottles are numbered, and the steps are detailed, so you won’t struggle to get the results right. Effective Results PH of tap water can change after a period of time: If you test the PH of tap water immediately after it flows from your faucet, it might read higher than you expect. The water in your pipes has a higher concentration of dissolved CO2 and this makes the PH reading high. Let a sample of tap water rest over 24 hours in an open container to off-gass this CO2, then test it. The result will be a more representative PH reading of your tap water. There’s a chart that explains all the steps that you need to follow while testing for different parameters.
