Copper in Swimming Pools: Causes, Effects & Solutions

Adjust the pH level. Copper levels can increase when the pH of the pool water is too high. Aim for a pH level between 7.2 and 7.6.

Reduce the amount of copper in the water. This can be done by using a copper sequestering agent, which binds to copper ions and prevents them from dissolving in the water.

Replace the pool water. If the copper levels are too high, you may need to replace the pool water.

Contact a pool professional. If you are unable to resolve the problem yourself, contact a pool professional for help.
