Calcium deposits, also known as scale, are a common problem in swimming pools, manifesting as a white or grayish crust on tile surfaces. This occurs when calcium carbonate precipitates out of the pool water due to elevated pH levels, high water temperatures, or excessive calcium hardness. The resulting buildup is unsightly, can harbor bacteria, and eventually damage the tile surface.
Addressing mineral accumulation on pool tiles is essential for maintaining the aesthetic appeal and structural integrity of the pool. Early intervention prevents the buildup from becoming severe, which could necessitate costly professional cleaning or tile replacement. Maintaining proper water chemistry also prevents this issue, prolonging the life of the pool’s surfaces and reducing maintenance costs.
