I've A Saltwater Pool..pH Is High

All my pools the pH is high and I've done everything I could to bring it down but nothing is working.

Do you have any suggestions

Thanks for your question, but unfortunately the question doesn't give me enough information to give you a reasonable answer.

What do you mean by "I've done everything"? Have you used muriatic acid? If so, how much? When did you add it and how long after the application did you re-test? What where the results? What are the readings?

What is meant by "high pH level"?

How big is your pool?

As you can see there's many questions that need to be answered before I can give you a solid answer to your question.

You can resubmit a question with those answers provided and we can go from there.
