I hope it is getting better today. Since you are still getting a CC reading, I would continue to maintain shock levels with your chlorine. If you had a lot of algae, the cloudiness may just be the sand filter taking awhile to filter out the dead algae. Some people with sand filters have had some luck with adding a little DE to their sand filter to help clear it. Poconos does that. I'll alert him to this thread and see if he thinks that might be something that could help you. Hang in there. It will clear up. Post with any changes today.
