Testing the Waters
In order for fish to thrive, water must be similar to that which could be found in their natural environment. Poor water quality can cause fish stress, illness and even loss. Most common water quality parameters are Ammonia, Nitrite, Nitrate, and pH. All may vary over time and all are invisible to the eye which is why it is important to test weekly. Testing aquarium water weekly will aid in keeping your most important water parameters within the proper range for your aquarium. Choose from a wide range of API testing options, such as our popular FRESHWATER MASTER TEST KIT or 5-IN-1 TEST STRIPS, for accurate water evaluation. Regular testing will help you easily determine your aquarium conditions.

Product Description
Keep your fish healthy and thriving by testing your aquarium water's pH regularly with easy-to-use API Freshwater Aquarium pH Test Kit. Testing water parameters weekly helps prevent invisible water problems that can be harmful to fish. pH is the measure of acidity of water, on a scale ranging from 0 to 14. A pH of 0 is the most acidic, while a pH of 14 is the most alkaline. Different geographies have different tap water conditions with different pH levels, while fish require a specific pH level to thrive. A pH of 7.0 is ideal when keeping a community aquarium containing a variety of tropical fish. Goldfish and livebearers prefer a pH of 7.5. Many Amazonian fish, like angelfish and neon tetras, prefer a pH of 6.5 to 6.8. Mollies and swordtails thrive at pH 7.2 to 7.5. API Freshwater Aquarium pH Test Kit contains 1 pH test bottle, instructions, capped test tube, and color card for easy pH level testing in freshwater aquariums. API Freshwater Aquarium pH Test Kit test a wide range of pH levels from 6.0 to 9.0. Use the color-coded chart to determine if your water is safe or if adjustments are needed. Then follow the recommendations to treat the water – it's that simple!

Important information
Directions
Directions: push down on cap while turning to remove childproof safety cap. Fill a clean test tube with 5 ml of water to be tested (to the line on the tube). Add 3 drops of pH test solution, holding dropper bottle upside down in a completely vertical position to assure uniformity of drops. Cap the test tube and invert tube several times to mix solution. Read the test results by comparing the color of the solution to the pH color card. The tube should be viewed in a well-lit area against the white area of the card. The closest match indicates the pH of the water sample. Rinse the test tube with clean water after use. A pH of 7.0 is ideal when keeping a community aquarium containing a variety of tropical fish. Goldfish and livebearers prefer a pH of 7.5. Many Amazonian fish, like angelfish and neon tetras, prefer a pH of 6.5 to 6.8. Mollies and swordtails thrive at pH of 7.2 to 7.5. To raise or lower pH in a freshwater tank, use API pH UP or pH DOWN. To automatically adjust pH to a preset level, use API PROPER pH 6.5, 7.0, or 7.5.
