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.
Step 2. pH-A high pH level causes your filter to work harder and the chlorine in your pool to be inefficient. It can also cause cloudy water, scale on the pool walls and floor, discoloration of the pool's surface and eye/skin irritation.pH should be maintained within 7.2-7.8 with a reading of 7.4-7.6 being ideal.tep 3. Alkalinity-Alkalinity works with the pH to increase the chlorine's efficiency. Alkalinity also helps prevent the pH from drifting or bouncing. High alkalinity causes cloudy water, scale on the pool walls and floor, discoloration of the pool's surface and eye/skin irritation.
