Haven't had cloudy water in a while. The last time it was an algae problem...this time not so sure. My levels seem normal, no combined chlorine at all.

What I will say is that my pool was dirty. It's been too cold to go in lately so I haven't vacuumed for a while but I have been maintaining my chlorine levels, etc. I just purchased an automatic vacuum (end of season sale) and I threw it in the pool today. It's been vacuuming all day and is doing a pretty good job considering the amount of dirt and leaves that were sitting at the bottom of the pool. I'll probably vacuum a few more times this week, and tomorrow it's suppose to be high 70's so I was gonna actually go in and brush my walls, etc.

Trying to get everything ready to close, but I don't want to close a cloudy pool. Been strictly BBB this year. Should I shock it even though my tests don't seem to give any indication of any algae bloom?
