Does Oxone® affect pH?
Because Oxone® is acidic, products containing it can lower pH. If you use an alkaline sanitizer such as calcium hypochlorite, Oxone® helps offset the upward drift of the pH level. For a neutral sanitizer such as dichlor, Oxone® lowers pH slowly. To adjust the pH level, add one pound of sodium bicarbonate for every four pounds of Oxone®. Some Oxone® products are preblended to have a neutral pH. These products should not affect pH or alkalinity.
