Every week pond owners need to check how high the pH-value is and whether there is still enough carbonate hardness (KH) to keep the pH-value stable. Both values are basic requirements of a functioning pond and can be easily tested in a few minutes. You don't have to be a specialist for this! Since the pH-value rises during the day and falls during the night, a test in the morning and in the evening is highly recommended!
