How do I get rid of metals from my pool water?

1. Sequestering agents: Sequestering agents bind to metal ions, preventing them from reacting with other chemicals in the water. This can prevent the metals from causing stains or scale. Some common sequestering agents include EDTA, NTA, and DTPA.
2. Chelating agents**: Chelating agents are similar to sequestering agents, but they bind to metal ions more tightly. This can make them more effective at removing metals from pool water. Some common chelating agents include citric acid, oxalic acid, and gluconic acid.
3. Reducing agents**: Reducing agents can convert metal ions into their elemental form, which can then be filtered out of the water. Some common reducing agents include ascorbic acid (vitamin C), sodium thiosulfate, and ferrous sulfate.
4. Oxidation-reduction potential (ORP) controllers**: ORP controllers measure the ORP of pool water and automatically add chemicals to keep the ORP at a level that inhibits metal corrosion.
5. Water filtration**: Filtering pool water can remove metals and other particles from the water. Cartridge filters and sand filters are the most common types of filters used for swimming pools.

The best way to remove metals from pool water will depend on the type of metal and the concentration of metal in the water. If you are not sure what type of metal is in your pool water, you can ask your pool service professional for help.
