Just an update:
FC is around 20
PH - 7.4
Alk - 80
CYA - 70

I changed out my filter and pump. It's a Hayward ST166 filter with a 1HP pump. I used a generic Zeobrite media in the filter and the pool is clearing a bit more each day, but still taking its sweet time.

My question is how long do I keep the shock level up, especially if the water is no longer green and I can see the botton print on the liner???

If it were totally clear I would have my answer, but it's not.
