- 1). Check your pH and alkalinity levels weekly, after heavy usage, after heavy rainstorms and after processing other chemicals through your pool. The most efficient way to test the alkalinity level is using test strips or kits that you can purchase at a pool supply store. Follow the manufacturer's instructions for using the strips.
- 2). Read the test strip and compare it to the chart provided by the test strip manufacturer to determine how much muriatic acid is needed to lower the pool's alkalinity to an appropriate level.
- 3). Pour the required amount of muriatic acid into the deep end of the pool in front of the return jet to get good circulation of the acid through the pool water.
- 4). Test the water again after 24 hours. Do not use the pool until the alkalinity level is in an appropriate range.
