Keep shocking if CC is 0, chem is ok, but water is cloudy?

[sws1]

Opened pool on Friday. Got all levels where they need to be, and am keeping FC at shock level. Water is still cloudy, but getting better every day.

Do I need to keep at shock level until the sand filter clears everything up? Or am I to lower FC to normal levels now the CC is at 0?

I think it's the former, but just checking.

(I still need to vacuum some sludge off bottom and sides.)

My details:
25k inground, vinyl pool.
CYA 50
Ph 7.4
TA 110-ish
CH 220
Used CalHypo to shock until CH was above 200, now using 12.5% liquid chlorine.
Sand filter

Keep the pool at shock level until you pass the overnight chlorine test. Then you will be good.

Perform the overnight chlorine loss test.

3 criteria to stop shock
1- hold FC overnight (<1 ppm drop)
2- <.5 CC
3- water is clear


You should hold shock until water is clear- with CYA in the pool, it shouldn't be hard to maintain
You can add alittle DE to the sand filter to help clear the pool...
