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.
I know that at my school, we check the water every hour. I believe that is NY State law. We change the water twice a year. The board of health comes around periodically to check our logs.
