Controlling pH
NOTE: At a pH of 8 only 25% of your chlorine will be an effective sanitizer. It will get worse as pH
increases - at a pH pf 8.5, less than 10% of your chlorine is active. The other 90% is completely
wasted. Keeping your pH between 7.2 and 7.5 maximizes the power of the chlorine and makes the pool
comfortable.
The pH is a measure of acidity of pool water. A pH less than 7.0 is acidic, a pH of 7.2 is neutral and a pH greater
than 7.6 is alkali. The operation of the chlorinator tends to remove hydrogen from the water and hence pH will
trend upwards. It is likely that acid and buffer will need to be added periodically. Failure to do so will cause
uncomfortable stinging in eyes, excessive scaling of the electrodes and heavy demand on chlorine. This in turn
will cause excessive running of the equipment and needless cost.
To decrease pH, add water to a bucket then dilute 1 part swimming pool hydrochloric acid for 2 parts water. Add
the mixture to the pool water. Use a test kit to determine the amount of acid to add.
To increase pH, add sodium bi-carbonate
Total Alkalinity
Total alkalinity is a measure of the buffer that will resist changes to the pH. A high TA will assist with maintaining
the correct pH level. Add pH buffer to increase or acid to decrease.
