Update:
On Tue evening, I added DE to the filter and went through a few cycles of that, and let it run all day yesterday.
Got quite a bit of rain on Wed, but came home and the water was very blue and the clarity was much better.
I tested last night and the FC was 8.5, so I added a gallon of 8.25% to get it to 11.5 (CYA is still around 30).
Didn't run any DE last night. This AM:
FC: 10
CC: .5
CYA: 30
The water is still nice and blue, the deep is still a little cloudy, and I am still getting the brown spots. Here are some pictures:
The first 2 are what it looked like earlier in the week when I was worried it was getting greener:

Here is what it looked like on Tues morning before the DE (I think):
