    Help with Ph and TA

    I am new to this game. The pool has been turned over to us for about two weeks now. My numbers are as follows: FC 3.5, Cya 80, TA 340, and PH 8.2. How do I control the TA and PH? And what dose of what, do I need to use to get these numbers down? We have a salt water pool and it is 27,000 gallons. The salt level is 3200. I appreciate the advice in advance, just trying to learn how to control it all!

    Re: Help with Ph and TA

    How much of Pool School have you read? The are articles that explain the different chemicals used to achieve certain things and how to add them.

    You need to use muriatic acid to lower the pH. Use PoolMath to calculate how much to use. When you lower the pH, that will also slowly lower the TA. There is another article which explains how to actively lower the TA by alternating acid and aeration.

    Start Pool School by reading "ABC's of Pool Water Chemistry"
