pH. The pH is a measure of the acidity of the water. The pH scale goes from 0 to 14, where pH 7 is neutral. If the pH is above 7, the water is basic; if it is below 7 the water is acid. The optimum pH for pool water is 7.4, since this is the same as the pH in human eyes and mucous membranes. A pH of 7.4 also gives good chlorine disinfection.
this morning chlorine is now below 10. PH test is still bright orange. IS this high? I am confused because on the sample tube, light orange is at the low end and bright pink is on the high end. My color is definately an orange, but very vivid. Even when doing the acid demand, I can't match a color on the tube.
