High levels of metals, particularly copper or iron, can lead to staining on pool surfaces. When these metals are present in the water, they can oxidize and precipitate out of the solution, resulting in discoloration and stains on surfaces such as pool walls, floors, and even fixtures. This staining commonly appears as green or reddish-brown spots, depending on the type of metal involved.

Maintaining balanced water chemistry and regularly testing for metals is essential to prevent these issues and ensure the longevity and aesthetic quality of a pool. Other factors, such as low pH levels or insufficient chlorine levels, may affect water quality and swimming safety but do not directly cause staining. Poor filtration can lead to cloudiness and contaminants but does not specifically correlate to the staining caused by metal buildup.
