Calcium

Why is calcium hardness important to pool water chemistry?

Pool calcium hardness is important to pool water chemistry because it helps to prevent scaling and build-up of minerals on the surface of pool walls, floor, and fixtures.

When there is not enough calcium hardness in the water, it can result in etching of surfaces and corrosion of plumbing systems. In addition, having the proper amount of calcium hardness helps keep other factors like alkalinity and chlorine stable, which are also important for proper water chemistry in a swimming pool.
