As much as hard, unconditioned water can be a pain in the house, the water experts from Green Water Technologies say that it’s actually better when filling a swimming pool. This is true, but water that’s too soft can be a problem, too. As with most things, it’s all about balance.
According to Green Water Technologies, pool walls and floor can take on a white brownish appearance when exposed to hard water. Mineral content determines color, and these deposits can leave stains that won’t be easy to remove. Excessively hard pool water may even have small crystalline deposits scattered throughout, and the ladder and any toys left in contact with water can become discolored. This is because the magnesium and calcium minerals will stick to any surface available. The chemicals you use in your pool try to create a balance and what isn’t needed will seek out a new “home.”
