Saltwater pools are filled with saltwater rather than chlorinated water. It so happens that salt naturally contains chlorine. You therefore use natural chlorine to take care of your pool. What are the advantages of saltwater pools? Simple and efficient, generators work on the principle of electrolysis, and will break down the salt present in the water into chlorine and sodium. These salt systems have the advantage of not provoking eye irritation and not having an unappealing odour. They are not compatible with all types of pools.
