why adding chemicals to the pool water is done instead of draining and cleaning

Question

I see a lot of videos of cleaning pools and I don’t understand why heavily dirty pools aren’t just drained instead of adding things to it. Is it cheaper? Aren’t the chemicals harmful? Is the concentration harmful?

Water can cost a lot. To fill a 20k gallon pool from a water tanker delivery would be about $600-$800. There is also a small chance of the concrete shell rising out of the ground due to ground water pushing from below. It has happened.
