I'm new to the pool world and have done some research and think I have a pretty good handle on the chemistry side of things. One question I do have, if my SWG is set to run x- amount of hours a day per the pool size. Do I need to be concerned about turning it down on weeks or longer period of times when my pool will be unused ? I plan to have my pool covered and there will be a time when it goes unused for several days. My thinking says that if it is covered and unused that I will get a spike in chlorine if the swg continues to run on the normal schedule.
