How to Lower the PH Balance in Pools
Maintaining and regulating the pH levels of your pool is essential in order to have a safe and healthy swimming experience. The ideal pH level for your swimming pool is somewhere between 7.2 and 7.6. Anything that goes into your pool water can change the pH level (especially rain), so your pool should be checked several times a week. If the pH level gets too high, it can easily be lowered by adding the right chemical. Does this Spark an idea?
