The sparkling, clear pools of our villas could make you feel as if you have your own slice of paradise. And plunging into the cool water is a refreshing way to escape the reality of a hot summer day. In the sections below, we will explain the differences between our saltwater system to maintain the pools and the traditional chlorine 1 system.
Chlorine and Salt Levels
It is a common misconception that saltwater systems do not have chlorine 1. In fact, these systems are currently the most popular of the chlorine systems. A saltwater pool will have lower levels of chlorine than a traditional chlorine pool because the chlorine is produced at a steady level rather than added to the pool with chlorine sticks or tablets. Salt is added to the pool instead, and a saltwater generator produces hypochlorous acid for sanitation through electrolysis, which is the breakdown of the salt by passing electricity through the saltwater solution.
Despite the name of a saltwater pool, the salt content is approximately that of human tears, about one-tenth the salinity of ocean water. Swimmers can open their eyes underwater, and their skin feels softer after a swim.
The lower chlorine concentration of a saltwater pool will be gentler on a swimmer’s skin. This is a particular benefit to swimmers with allergies, but anyone will enjoy smoother skin when swimming in the pool. The lower level in a saltwater pool also reduces swimsuit fading. Chlorine in a traditional pool is higher in concentration and can cause the skin to itch, burn, and become dry.
As an added health benefit, storage of salt requires no special considerations, but chlorine must be stored in a cool, dry, and well-ventilated location with regards to maintaining its effectiveness and preventing hazards to homeowners who might breathe the fumes of the chlorine products.
Perhaps the greatest benefit of a saltwater system to homeowners is the low maintenance the pool requires. The most up-to-date systems can maintain a clean and sparkling pool for up to two weeks without intervention. By contrast, a traditional chlorine pool requires weekly maintenance with chlorine 1 tablets or sticks added regularly. Both pools will need the chlorine level checked on a regular basis to keep the chlorine level within the correct zone for having a clean, clear pool. The difference is that a saltwater pool’s chlorine is adjusted at the generator control box and by adding more salt to the water. By contrast, the chlorine system must be adjusted by the amount of chlorine physically added to the pool.
The chlorine pool will also need periodic “shocks” of more concentrated chlorine to ward off algae and maintain consistent chlorine levels. This involves dissolving chlorine in a bucket of water and adding it slowly to the pool. A saltwater pool needs this shock treatment less often, usually only after an especially heavy rain or when algae begin to bloom, making the pool turn green.
