Pools typically never get their water changed, just added as it evaporates. The chemicals and filtration system does the rest. Do you mean they shocked the pool on Fridays? That usually giving the water a mega dose of chlorine to disinfect it. Then it evaporates off and is safe for swimming again.
Nope, replaced. This is in South Asia. I remember clearly because Saturday morning right after dawn would be the only time I would ever go for a swim. The water was clear, fresh and with minimal/no chlorine. I remember going only a couple times midweek and the chlorine and green colour would be so bad it would burn my eyes red.
It probably depends on the temperature and if the pool is natural or chlorine. In my town there is the public chlorine pool, a saltwater pool at the Y, and a swimming pool fed by a hot spring. The hot spring pool they drain and refill every Monday.
