Update:
I added some DE to the sand filter last night. (About 4 or 5 solo cups)
I back washed a few times prior so I had to add some fresh water. FC is now 16ppm, CC is now ZERO and pH is 7.4. The filter pressure climbed 11 psi and flow was pretty slow so I back washed again this afternoon. Results are still the same. This cloudy water isn't getting any better at all. It still looks exactly the same. How long should it take to see results from adding DE? Did I add enough DE, too much? This is starting to get a little frustrating to say the least.
