Anyone knows how public swimming pools are maintained? Do they completely change the pool water at the end of day, or weekly? Anything they do to the pool overnight (just circulate like daytime, or do nothing, or change entire pool water)? Is the water cleaner in early morning than evening because of this? Thanks.
most pools lose enough water through splashes, people and evaporation that they're being refilled pretty regularly. now that is probably only a couple hundred or couple thousand fresh gallons being added at a time, but it indeed does help. some places do this automatically; others you have to manually turn on the fill spout near the diving well.
Pools are generally a bit clearer every morning for the sheer fact that they've been sitting for several hours with no (or if outdoor, few) impurities entering, and the filters have had a nice chunk of time to turn the water over.
