Hold the strip horizontally, or lay the piece down, making sure the color pads are facing up, and the strip is not in direct sunlight. But its not always easy to keep it there. Chlorine dioxide-generating sachets placed in the primary package have been shown to preserve the quality . Alkaline water (high pH) is a totally different thing in itself and it is measured on a scale level (pH level). High ORP levels indicate that the chlorine is properly disinfecting the water and getting rid of impurities. While colorimetric tests provide users with accurate measurements, they arent ideal for real-time measurements.

Most large pool owners agree to keeping a well-balanced pool TA (Total Alkalinity) needs to be in a solid 90-100 ppm range. The purpose of a piped treatment system is to provide proper disinfection at the numerous endpoints throughout the system, which are usually water taps. A good chlorine level is between 1.0 and 4.0 parts per million (ppm), while the pH should be between 7.2 and 7.8. 4.
