Restoring swimming pool water is one of the most important parts of being a pool owner. This requires good chemical balance to prevent the formation of algae and skin irritation from bad chlorine levels. If the pool chemical balance is not taken care of and the pool is not cleaned properly, you may see black or green forming on the liner or notice your skin turning red after swimming. This means you need to restore your pool water.
Take a sample of water from about 18 inches below the surface and place the water into the vials of your pool testing kit. Place the recommended drops of chemicals into the vials and shake them. Compare the color of the water to the color chart in the testing kit to determine the chlorine level and pH. Pool pH should be 7.4 to 7.6. Chlorine should have a free level of 1 to 3 parts per million (ppm).
Add soda ash to your pool water if the pH is below 7.4. Use the chart on your pool testing kit for the recommended amounts for your pool.
