After being away for 3 days, we returned home on Tuesday only to find our pool cloudy & pea green (heavy rainfall in the morning).

I followed the "best guess CYA chart" and shocked to 15ppm using 12.5% pool shock. I've maintained this level ever since.

On Wednesday, I vacummed the pool and backwashed the filter

Yesterday morning (Thursday), the pool was no longer green, but it was still cloudy. I was hoping that the pool would be clear by Friday morning.

Today (Friday morning) the pool is still cloudy! Here are the parameters today:

FC: 15.0
pH: 7.6
CYA: 50
Alk: 100

Should I remain patient, or do I need to do anything else?
