One week ago my alkalinity was 200 so we put in muriatic acid. Well, we added it gradually over 2 days but didn't know to check the pH. So of course, we got extremely low pH and then lots of algae. We have shocked it over 3 nights and finally it looks like the algae is gone but the water is still really cloudy. This morning Free Chlorine is around 30, pH is 8.0 and alkalinity is 110. I know I need to lower pH but don't want the alkalinity to go below 100. I feel like it's a yo-yo effect going on. What should I do?
