Matt, you have received wonderful advice thus far.
Keep shocking your pool. Hold it at shock level as best you can. The weekend is (almost) here. Maintaining shock level at night is great (if you can do it) since the sun cannot steal any of the FC fighting organics.
Keep at it and get another bottle of POP (pool owner patience) and the job will get done.
What test kit are you using? (sorry if Imissed it)

pool still green and cloudy. 4 days and counting.
again, not questioning your practices but how come granular shock used to wipe this out in 1-2 days? i appreciate everyone's help, i just don't understand why chlorine isn't doing the same thing
It has been cloudy since at least December 2008 (your words from your sig) and it ain't gonna clear overnight. The only thing the granular shock did was give you a false sense of hope (i.e. temporary fix) and did not address the problem. The problem will be cured if you are willing to stay with us to the finish with TFP instructions.
Do yourself a favor and stick with bleach or liquid chlorine. No side effects to possibly worry about later.
You can do it and you will have a wonderful pool to show for your efforts.
