API High Range Test Kit Fresh/Saltwater
The API® HIGH RANGE pH TEST KIT measures pH changes in marine aquariums, aquariums with African Cichlids, and very alkaline tap water. The API HIGH RANGE pH TEST KIT reads the pH of water within the high range of 7.4 – 8.8, and includes one bottle of test solution and one test tube.
Contains 160 tests and includes 1 test bottle, easy-to-ready instructions, glass test tube and color chart
Why Test pH?
pH is the measure of the acidity of water. A pH reading of 7.0 is neutral. A pH higher than 7.0 is alkaline, and a pH lower than 7.0 is acidic. Maintaining the aquarium at the proper pH ensures optimal water quality. The pH should be tested weekly since natural materials in the aquarium (such as fish waste and uneaten food) can cause pH changes.
The minimum pH reading for this kit is 7.4 and the maximum is 8.8. Under extreme water conditions, readings below the minimum will read 7.4 and above the maximum will read 8.8. pH adjustments outside the range of this kit will not show any changes until the pH of the aquarium water is within the range of this kit.
1. Fill a clean test tube with 5 ml of water to be tested (to the line on the tube).
2. Add 5 drops of High Range pHTest Solution, holding dropper bottle upside down in a completely vertical position to assure uniformity of drops.
3. Cap the test tube and invert the tube several times to mix the solution.
4. Read the test results by comparing the colour of the solution to the appropriate high Range pH Colour Card (choose either Freshwater or saltwater). 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.
