The Battle of Pool Systems: A Comparative Dive
Salt Water Pools: A Wave of Benefits for Pool Owners
Riding the Salty Tide: How Salt Systems Work
While swimming in a saltwater pool might conjure images of frolicking in the ocean, the reality is quite different. Salt water pools rely on a salt chlorine generator, transforming sodium chloride (salt) into hypochlorous acid – the same sanitizing agent in regular chlorine. The generator’s salt cell works magic by electrolyzing the salt, producing just the right amount of chlorine to keep your pool crystal clear and sparkling clean.
To understand the difference between saltwater pools and ocean water, consider the disparity in salt concentrations. This distinction greatly impacts the swimming experience and maintenance requirements for saltwater pools.
Salt concentrations in saltwater pools typically range between 2,500 and 3,500 parts per million (ppm). This salinity level allows the salt chlorine generator to convert sodium chloride into chlorine effectively, ensuring your pool stays sanitized. The lower salt levels in saltwater pools lead to a more comfortable swimming experience, with reduced skin and eye irritation compared to traditionally chlorinated pools. Plus, the slightly salty water feels softer on the skin, offering a more enjoyable and natural swimming sensation.
On the other hand, ocean water boasts a much higher salt concentration, averaging around 35,000 ppm. This salinity level is approximately ten times higher than a saltwater pool. Swimming in ocean water can sometimes result in skin and eye irritation due to the high salt content. Moreover, the salt levels in ocean water create a buoyancy effect, making it easier to float.
Salt System Levels and Maintenance
A saltwater pool system requires regular maintenance but is typically less labor-intensive than traditional chlorine pools. You must monitor and adjust the salt, pH, and alkalinity levels to keep your pool in tip-top shape. Additionally, depending on usage and maintenance practices, you’ll need to clean and replace the salt cell every 3 to 7 years.
