the higher pH is not good, you need some acid to bring it down- slowly! I'd add maybe a cup at a time, retest in an hour (with pump on!) and add little more (or next day) til you got it down to 7.6 or so...
don't think there's a shotglass method for pH, because the scale is logarithmic
With your CYA level, FC of 25-30 is shock level and is safe
