New pool owner here. (see first thread -- has photo of how foilage heavy our pool is, with branches overhanging ~1/4 the surface area of our pool)
We usually keep the pump running 24/7 to keep debris and water quality manageable, even when we go to bed for the night with the pool cover on (for algae management) and when pool cover is off (for foilage debris management too). Except when I heated up the pool but turned off the heater and want to preserve the heat overnight, I turn off the pump to prevent the cold ground from cooling down the water as it's pumped (I feel cold water coming out of the jets, half an hour after I turn off the pool heater -- indicating the ground is cooling down the water).
I have an issue of foilage and lots of debris in the pool, so running the pump allows a lot of debris to reach the skimmer eventually. But may want to cut back a bit next year, as I've reliably kept the pool clear and will also be getting better test kits too.
Do other people with foilage-heavy swimming pools, have recommendations on how to cut back the pumping? Perhaps turn off during the expensive electricity rates (TOU) -- but keep it running at all other times and during the weekend when people are using the pool? I'm wondering how surface debris builds up if you don't run the pump 24/7.
