Use to measure pH changes in marine aquariums, aquariums with African cichlids, and very alkaline tap water.
Reads the pH of water within the high range of 7.4 to 8.8. 160 tests per kit. Freshwater/Saltwater High Range pH Test Instructions
Why Test pH? pH is the measure of 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. Certain freshwater fish thrive at a pH above 7.0. Live-bearers and goldfish require a pH of 7.5. African cichlids, marine fish and invertebrates require a pH between 8.2 and 8.4. Maintaining the aquarium at the proper pH ensures optimal water quality.
Testing Tips: This test kit measures pH from 7.2 to 8.8 in either fresh or saltwater aquariums. This kit contains two High Range pH Test Color Charts: one for freshwater aquariums, and one for saltwater aquariums. So be sure to use the correct chart for your type of aquarium when interpreting test results. The Freshwater pH Test Color Chart is the appropriate chart to use for testing freshwater aquariums to which aquarium salt and African cichlid salt have been added. Artificial salt water should have a pH of 8.2. pH can be raised using a commercial buffer or Sodium Bicarbonate (common baking soda/)
