I probably would. I would think most of the cloudy water is nearer the bottom. I mean, it all gets mixed together, but it's all about circulation, and maybe giving your main drain more responsibility would help keep it better circulated during the filtering process. I mean, we're talking small percentage improvement, but it could help.We had the main and skimmer open all the way. Two days ago, I closed 2/3 of the main drain off.
I can change it to the main drain all the way open and the skimmer 2/3 closed.
It's safe as long as you're below shock level (and good pH, and clear). But I'd let it drop below 10 in order to accurately test pH, especially if anybody there has sensitive eyes/skin.So once all three aspects of the slam are met, what does the FC have to go down to before it is okay to swim in? I will need to check the pH again too.
