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'm not sure about the local YMCA pools, I've never seen those shut down, but the town rec center I go to empties and does maintenance once a year in October for 2 weeks. There is a lap pool, kids area with slides, jets and fountains, plus an activity pool for water aerobics, etc. Those are all cleaned thoroughly, broken and worn things fixed, then refilled. Water temperature from the pipes is about 50 degrees, normal underground temps in the northeast. Consequently, it takes a few days for it to warm up again, so the shutdown is a little extended unless you can tolerate the cold. I waited 2 days after reopening and it was still around 70 degrees which, as an open water swimmer, I can handle.
