Re: Aeration and its effect on pH
You don't need calcium in a vinyl liner pool. Have you used algaecide? Some algaecides, especially if you have used a lot lately will cause suds. Your alk and ph are fine. If you are using trichlor tabs, it could be bringing your ph down. If you give a little more info on what you have been using in your pool, and a full set of numbers we can answer better.
