WebAug 5, 2011 · I do not recall all of what I studied, but I think that a system can be tricked into believing that the chlorine level is high, low, OK, or non-existant just by manipulating the PH. If you alter ONLY the chlorine levels, and the PH stays consistent, then you can use ORP as a relative chlorine indicator. WebChlorine too high: Reduce to between 600 and 650 mv ORP; Test Total Alkalinity and adjust to 80 to 120 ppm; If the ORP sensor is not immersed, you need to install the sensor chamber so that it is always in pool water.

For chlorinated pools and spas, a safe ORP reading is usually between 650 millivolts (mV) and 750 mV. As time passes and chlorine breaks down and loses its oxidation potential, the overall ORP reading for the water gradually decreases.
