I need to follow up with a newbie question.

I read that it's better to pour chlorine in the evening to avoid burn-off by sunlight.

About "hold it there", do I need to check every evening and pour the right amount **each evening**? Or do I check every hour or so and keep pouring in **throughout** the day for several days?

Thanks again.

Not every hour, but as often as is reasonable, definitely in the evenings. The more often you test and add enough bleach to get back to shock level, the faster this process will go.
