When it comes to pool sanitation systems, there are quite a few options available. The most popular are traditional chlorine and saltwater systems, and mineral systems. But what are the differences between chlorine, saltwater and mineral swimming pools? Does one keep the water cleaner than another? What's better for your pool? What's better for your skin and hair? Which is the most cost-effective? Of course, if there were just one perfect pool sanitizing system, there wouldn't be so many to choose from. But, like most aspects in building a pool, saltwater, chlorine and mineral systems all have their own sets of pros and cons - and which you choose will ultimately be up to what you value as most important.
