How do I balance my pool water?

Balancing pool water involves adjusting the levels of various chemicals to ensure that the water is safe and comfortable for swimming. The following is a general guideline for how to balance pool water:
  1. Test the water: Use a pool test kit to measure the levels of chlorine, pH, total alkalinity, and calcium hardness. Follow the manufacturer’s instructions for the test kit.
  2. Adjust the pH level: The pH level should be between 7.2 and 7.8. If the pH level is too low, add a pH increaser (such as sodium carbonate) to the water. If the pH level is too high, add a pH decreaser (such as sodium bisulfate or muriatic acid) to the water.
  3. Adjust the total alkalinity: The total alkalinity should be between 80 and 120 parts per million (ppm). If the total alkalinity is too low, add an alkalinity increaser (such as sodium bicarbonate) to the water. If the total alkalinity is too high, add a pH decreaser (such as sodium bisulfate or muriatic acid) to the water.
  4. Adjust the chlorine level: The chlorine level should be between 1 and 3 parts per million (ppm). If the chlorine level is too low, add chlorine to the water. If the chlorine level is too high, add a chlorine neutralizer (such as sodium thiosulfate) to the water.
  5. Adjust the Calcium hardness: The calcium hardness level should be between 200 and 400 parts per million (ppm). If the calcium level is too low, add a calcium hardness increaser to the water. If the calcium level is too high, add calcium hardness decreaser to the water.
  6. Check the Cyanuric acid (if using stabilized chlorine): It should be maintained between 30 to 50 ppm to prevent chlorine loss due to sunlight.
It is important to wait at least 4 hours after adding chemicals to test the water again to ensure that the levels are in the appropriate range. It is also important to follow the manufacturer’s instructions for any chemicals used in the pool and to use test kits that are specifically designed for swimming pools.
