The cloudiness can come from inpending algae, dust/pollen on the blanket, dead algae that needs to be filtered, too much cal-hypo added too quickly, or a host of other things. To rule out goo in the pool creating the chlorine demand, I would test my water at night for chlorine and CC, and test again in the morning before the sun is on the pool. If more than 1 ppm of chlorine was lost in non-sunlight, and/or the CC was over 0.5, then I would shock the pool again and hold it at shock level until it passed that test. If there was not more than 1 ppm chlorine loss, then I would look to the filter to filter out whatever was causing the cloudiness.

I would not worry about the pH at 7.2...that's fine, and the nature of a SWCG tends to run the pH upward anyway--I would leave that alone and not worry about it. I would also keep my chlorine levels higher than 1 ppm, to make sure I wasn't fighting algae all summer....
