Pool Basics: How To Conserve Chlorine

[@NCF8710]

Check the pH of the pool water. It should be between 7.1 and 7.3. When using phenol red as a test solution, the color will be orange if the pH is correct. The color will be yellow if the pH is too low and red if the pH is too high. If the pH is too low, you will be consuming chlorine at a high rate. There will be times when the chlorine level will fall to zero and algae will start to grow. If the pH is too high, the chlorine will become less effective. Use a DPD test kit for monitoring the chlorine level and maintain it between 1 and 3 ppm. Maintaining a clean, algae free pool will also extend the life of the DE in your filter.
