Green Water Technologies | Hard Water Better for Pool?

Green Water TechnologiesAs 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.”

Green Water Technologies explains that soft water can be a problem, too, especially for above ground pools. Calcium hardness is necessary to prevent water from leaching metal from the pool’s wall. This can happen in plaster pools, and calcium can also be pulled from tile grout. This exchange of minerals can lead to premature corrosion, and that’s a condition no pool owner wants to consider.

Testing is the only way to know if a pool’s water is in balance, explains representatives from Green Water Technologies. In addition to hardness, a testing kit, which is often available free at local pool supply and hardware stores, also looks for pH balance and alkalinity.

Green Water Technologies explains that water softening products may not be enough to consistently remove hardness. Calcium is easy to add, however, and calcium chloride is available at most pool retailers during the spring and summer.
