Remove rust from your swimming pool by shocking the water and vacuuming the precipitated rust. The required supplies are a water testing kit, shock treatment packets, chelating chemicals and a pool vacuum. Although the time required varies with the size of the pool and the amount of rust it contains, most treatments take about a day.Continue Reading
Use the water testing kit to verify that iron is the source of the problem. Test the pool's chlorine level as well.
Add shock chemicals to the pool. The appropriate amount depends on the size of the pool, its chlorine level and the recommendations of the pool manufacturer.
Inspect the pool several hours after shocking. When the floor is covered in rust particles, vacuum it.
Retest the water and shock the pool again if necessary. Repeat the cycle of testing, shocking and vacuuming until the water is clear and the pool floor is clean.
Prevent rusty water with regular doses of chelating agents. These chemicals bind microscopic iron and copper particles into bundles easily removed by your pool's filtering system. Regular filter cleaning maximizes the benefits of chelating agents and keeps your pool water rust-free.
