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.
Thanks to the replies! That is so informative! I had thought they drain the pool every day, or at least every week! How laughable! Though in theory one could catch disease from a public pool, I haven't heard of real instance yet, so maybe most pool are ok... Whatever, we have no choice...
