Keep the chlorine at shock level since you still are showing a CC of 1.0. I'd keep the cover at least partially open when shocking to vent the pool. Fumes can damage the cover.

Hardness is an issue when it is high; it can cause cloudy water problems especially when you also have high TA, but since you still have CC, for now, you have to assume that your cloudiness is from fighting something in the water.

By the way, there is no CYA in your tap water.

Thanks for the testimonial and kind words! We appreciate them.
