One of the most important steps of swimming pool maintenance is water balance. Because of its complexity, some new pool owners may not know everything they have to do to keep their pool water safe, comfortable and corrosion free. If you are using either a salt based pool producing chlorine or a chlorine based tablet pool, then your pH needs to be correct. If pool water is not balanced correctly then the chlorine sanitizer won’t be working at full strength killing germs and bacteria. Your water balance needs to be correct or it will affect your skin and eyes. The pH should be neither too acidic nor basic in order to feel comfortable. An imbalanced pool can be corrosive to the liner, ladders and hand rail and other equipment such as the pump. Optimal Ranges
pH | 7.2 – 7.6 | |
Total Alkalinity | 120-150 parts per million | |
Calcium Hardness | 200-250 parts per million (Concrete Pools) | |
Calcium Hardness | 175-225 parts per million (Vinyl Pools) | |
Free Chlorine | 1-3 parts per million | |
Free Bromine | 3-5 parts per million | |
Metals: Copper | 0 parts per million | |
Metals: Iron | 0 parts per million |
