Once i enter the maintenance phase is there a recommended time of day to run the pump/filter? With swimmers, without swimmers, morning, evening, night, other? I will start by running about 8 hours daily.
Pump run time is all about skimming and chemical addition. As you do not show a SWCG, you will be adding liquid chlorine every day. So be sure to run the pump for an hour or so after adding the chlorine.
With lots of swimming, you actually need less pump run time in your case. But running the pump 8 hours per day should be fine.
I am curious as to why? I routinely run while swimmers are in the pool. One I have a slide and the pump sends water to the slide. Second, I like the water moving with swimmers (not sure I have a good reason for that other than a personal preference).
