One of the most important steps of swimming pool maintenance is water balance to keep the pool/spa water SAFE. either salt based pool producing chlorine or a chlorine based tablet pool, pH needs to be correct.If pool water is not balanced correctly then chlorine sanitizer won't be working on killing germs and bacteria that can cause diarrhea/ear/skin infections. COMFORTABLE. water balance needs to be correct or it will affect skin/eyes.pH should be neither too acidic nor basic in order to feel comfortable CORROSION-FREE. imbalanced pool can be corrosive to the liner,ladders/hand rail and others like pump CL2 can also get eaten up if lot of nitrogen (from debris,pee,sunscreen,sweat).It is best to test CL2 and pH levels all the time as they change daily depends on pool usage. High alkaline water leads to high pH.Low alkaline water leads to low pH.Keeping your pH levels w/in proper range is important for keeping your equipment and pool finish intact.Your chlorine will dissolve quicker with low pH level.High pH levels make chlorine inactive.
