Your Chlorine needs to be at an absolute minimum of 5 ppm unless you want algae to start growing--but because it's been low for a few days, especially with the rain in between, I think you probably already have algae blooming, which is why your pool isn't clear. Raise your chorine to shock level and hold it there to clear it up, until you're not losing chlorine overnight.

Test this morning:

65 FC
5 CC
7.2 PH

55 CYA

Try those chlorine tests again. I seriously doubt that your FC is 65 and your CC is 5. Re-run those and then repost. Everything else looks ok.

If you are using a 25 ml sample size, you need to divide the number of drops by 5 (i.e. multiply by 0.2) to get FC and CC levels. If you are using a 10 ml sample size, you need to divide the number of drops by 2 (i.e. multiply by 0.5).

This morning after I ran the numbers, I went to the pool calculator and used it. I added 4 gallons of 6% bleach. My numbers right now are:

FC 15.5
CC 10
PH 7.2
TA 100
CH 360
CYA 55

Still cloudy as it has been since day 1 after shocking. Do I need to bring the FC to 20 and try holding it there?

Yes, with your CYA at 55 ppm, you need to bring FC to 20 and keep it there until you're not losing any chlorine overnight. How are you measuring the CC? Your FC+CC=TC, but there's no way to have a CC of 10 unless your pool is a total swamp....
