Given: a 12000 gallon pool, a pH of 7.6, a FC of 4 to 5 ppm a CC of 1 to 2. I shocked yesterday with 1.5 # of 67% hypo and the water went a little cloudy but i could make out the drain ring in the bottom of the pool. This morning the cloudy is about half as cloudy as yesterday but the CC is still not down to what i would like. What to do?
CC 1 to 2 ppm

I see in another thread you have a TF100. I will assume you used that for those test results. It does not end in results with a range.
If you have a CC of 2, you have an organics issue in your water. If the water is cloudy, that most likely means algae.
EDIT - Cal Hypo should be a crime to sell in the Phoenix area. Do not use products that contain calcium. That may have also contributed to your cloudy water if your TA is elevated. Please post a full set of test results.

Using TP-100, Currently: FC is at 4-5 ppm, pH 7.6, CH 250, TA 110, CYA 80, the CC is what I am having trouble with. The CC end point goes clear and then a slight pink tint reappears within 30 seconds again and again. should I ignore the successive reappearances? thanks.

yes. Once the sample goes clear (FC or CC), the test is over.
You show a FC as a range. That is not how the test works.
Your FC is far too low for the CYA level you have.
Target FC is 9-11 for 80 CYA. Absolute minimum is 6 or inviting algae issues. Unless you have SWG, then minimum is 4, target is 6. But don’t see swg in signature.
Chlorine/CYA chart
Keep an eye on your filter pressure. Cloudy water can cause the pressure on a DE filter to rise quickly.
Get some more chlorine in there.
