What does brown water in the pool mean in practice?
The phenomenon often occurs immediately after the addition of chlorine, which turns the dissolved metals into a visible precipitate.
When does it matter?
Continued chlorination without removing particles may perpetuate stains on the basin and burden the filter.
Which solutions are related to it?
Metals should be tested, oxidized sediment should be captured by filtration, and sequestrant or make-up water treatment should be selected.
