We just had a nasty storm go through so I fished a branch out of the pool, emptied the skimmer basket then checked chlorine. It seems to be at 20. This is 2 hours after shocking. I think the weather is going to be fine till Sunday but, for clarification, if I thought there was a chance that skimmer and/or drains would get clogged or filter would fill, I should completely shut the pump down??? and not leave it on the timer (currently set for about 8 hours per day)?
