Your pH will not drop by simply stopping the aeration--you're going to have to add either dry acid or muriatic acid to drop it.
As far as your chlorine goes, less of your chlorine will be lost to the sun if you'll wait until dusk to add it.

Jan is right that the best time to add chlorine is in the evening, however, if you ever test in the middle of the day and find that you have no reading, don't wait to add it.
One other comment - with your calcium hardness at 300, no cal-hypo for your pool as it will cause the CH to continue to rise.
Re: pool store test results
is cal-hypo sodium-hypochloride? or what is it? I just added one gallon of 10% sodium hypochloride super chlorinating liquid to try to raise chlorine a little. was that the wrong stuff to add?
Re: pool store test results
No, cal-hypo is calcium hypochlorite. Bleach is sodium hypochlorite - usually 6%. What you added was fine. It will not raise your calcium hardness level.
