We put in a new blue liner this season and I noticed that this latest SLAM has started to prematurely bleach an area in our deep end (9 foot) that I also regularly see dirt and debris collecting. So--in short, I will spend longer time pouring liquid chlorine in front of the return moving forward and I'm also wondering what I can do to fix this circulation issue. Would it help to turn off/on skimmers/main drain when adding and/or change the direction of my returns to help with this?
