Yes. But why? I run mine at 40% and drop 1 quart of acid in it a week. I'm not sure what the problem here is? Any time you add Cl in any form, you are going to affect the pH:
  • SWC increases pH
  • Bleach increases pH
  • Di-Chlor/Tri-Chlor decreases pH
Running your pool at lower Cl levels is a sure way to create a problem waiting to happen, either with algae or sanitation. Run 3 - 5 ppm Cl, dump in the acid for the pH and be happy!
