The Importance of pH
You get the best out of your chlorine when the water is acidic. However, acidic water is agrgressive to teh bather and equipment, so the range we encourage is 7.2-7.4.
Even if the chlorine levels are reading 6, if the pH is greater than 7.6, then the desired effect of teh chlorine is deminished dramatically.
Testing with dipsticks isn't advisable as it is difficult to assrtain an exact pH reading, even at 7.6 the effectiveness of chlorine drops by 30% from 7.4. We therefore always recommend a simple comparator test kit, that allows you to compare the test sample to the clearer swatch, which gives you a more definative pH reading.
Just remember:
pH Minus reduces the pH; reducing the alkalinity of the water - hard water areas in particular
pH Plus increases the pH; increasing the alkalinity of the water - soft water areas
